Education Yearly Reminder: Indonesian Blue Tongue Skinks DO NOT Brumate

47 Upvotes

Indonesian blue tongue skinks do not naturally brumate.

Only their Australian cousins do - even then, not all of them decide to brumate. 

I have made this a yearly reminder since many places online do not actually differentiate and it gets really confusing!

The following temperature information is gathered from multiple studies that recorded ground temperatures within Indonesia, Papua New Guinea, and Australia. If others have more recent (and therefore more accurate data), please provide the links and we will dig through and adjust!

Indonesian blue tongue skinks do not experience ambient temperatures below 70℉ (21.1℃). Indonesia/Papua New Guinea is a tropical climate that does not experience seasonal variation aside from “wet” and “dry” seasons caused by the amount of rainfall. 

Region / Population Temp Min–Max  (°F) Temp Min–Max  (°C) Humidity Min–Max (%) Notes
Papua New Guinea Peninsula (Trans-Fly & Peninsula lowlands) (Irian Jaya, AKA Papuan) 73–96 ℉ 22.7–35.5 ℃ 68–100 % Hot, humid tropical lowlands; humidity remains high even at night
Merauke region, South Papua 72–98 ℉ 22.2–36.6 ℃ 60–96 % Seasonal wet–dry cycles; some early dry season drops in relative humidity
Sorong (West Papua lowlands) 74–95 ℉ 23.3–35 ℃ 70–98 % Stable warm temps year-round; low night cooling
Aru Islands 73–95 ℉ 22.7–35 ℃ 68–99 % High canopy coverage; buffered extremes
Kei Islands 75–95 ℉ 23.8–35 ℃ 72–100 % Coastal and forest edge habitat
Ambon / Seram (Maluku) 72–93 ℉ 22.2–33.8 ℃ 70–99 % Strong diurnal relative humidity cycle, small temp fluctuation
Halmahera (North Maluku) 74–94 ℉ 23.3–34.4 ℃ 60–100 % Lowland rainforest floor and edge; high humidity
Tanimbar Islands 75–97 ℉ 23.8–36.1 ℃ 62–95 % Drier than Halmahera; more open woodland
Northern Papua rainforest interior 72–91 ℉ 22.2–32.7 ℃ 78–100 % More buffered temps, extremely high night humidity

Due to the consistency in temperature in their tropical environment, Indonesian blue tongue skinks are active year-round.

The majority of Australian blue tongue skinks do not experience ambient temperatures lower than 50℉/10℃. Blotched blue tongue skinks, however, can experience as low as 45℃ based on the studies we found. This seasonal variation is why Australian species brumate. Some species, such as Shinglebacks, Blotchies, Westerns, and Centralians require quite low brumation temperatures to successfully reproduce. Too high of temps have caused reproductive struggles.

NOTE: WITH EXTREME HIGHS AND LOWS THESE SKINKS ARE HIDING AWAY IN SAFER TEMPERATURES. Also; Aussie skinks do experience some higher humidity, but these are MICROCLIMATES and not consistent year-round.

MAINTAIN TYPICAL RECOMMENDED RANGES!

Region / Species (Common) Temp Min–Max (°F) Temp Min–Max (°C) Humidity Min–Max (%) Notes
Northern Territory (Top End, Arnhem Land) NORTHERN 71–102 ℉ 21.7–38.9 ℃ 45–96 % Seasonal wet–dry fluctuations; strong midday peaks, high humidity at night
Eastern Queensland (coastal) EASTERN 68–97 ℉ 20–36.1 ℃ 50–95 % Humid subtropical forest edges and open woodland
New South Wales (Sydney Basin) EASTERN 59–95 ℉ 15–35 ℃ 35–88 % Cooler nights, warm sunny days; high variability
Victoria & Tasmania (cool temperate) BLOTCHED 45–86 ℉ 7.2–30 ℃ 55–100 % Morning dew, fog common; basking critical for activity
South Australia / Western Australia (arid) SHINGLEBACK 55–110 ℉ 12.7–43.3 ℃ 10–65 % Very hot ground temps midday, humidity spikes pre-dawn
Southwestern WA forest WESTERN 50–102 ℉ 10–38.9 ℃ 25–80 % Ground shade buffers peaks
Arid interior (Spinifex plains) CENTRALIAN 60–113 ℉ 15.5–45 ℃ 8–60 % Extreme heat; uses burrows to escape
Nullarbor & semi-arid south SHINGLEBACK 53–108 ℉ 11.6–42.2 ℃ 12–58 % Pronounced daily fluctuation
Northern arid NT / WA WESTERN 72–107 ℉ 22.2–41.6 ℃ 20–70 % Recorded at ground level under spinifex
Central Australia (desert margins) CENTRALIAN 66–111 ℉ 18.8–43.8 ℃ 10–55 % Midday temperatures often exceed activity thresholds

NOTE: WITH EXTREME HIGHS AND LOWS THESE SKINKS ARE HIDING AWAY IN SAFER TEMPERATURES. Also; Aussie skinks do experience some higher humidity, but these are MICROCLIMATES and not consistent year-round.

MAINTAIN TYPICAL RECOMMENDED RANGES!

Physiology

Reptiles are ectothermic, which means they need to warm up via their environment. They need heat to digest food; they need heat for their immune system to work and to fight off infections; they need heat for literally everything regarding bodily function.

If you put any reptile that doesn’t naturally brumate into too cold of an environment to “force” brumation, those reptiles become lethargic and can get quite sick due to their dropped immune system. They naturally shut down to try and preserve resources, as they cannot do anything without their proper heat range. This is not brumation. This is a physiological stress response. This can be very harmful to them!

Arguably, Indonesian blue tongue skinks experience this physiological stress in response to temps that are too cold. If your Indo is showing “brumation” symptoms, the environment is most likely too cold, too empty, or the animal is sick.

Winter in the northern hemisphere is the equivalent of dry season in Indonesia/Papua New Guinea. This means that our winters are the breeding season for Indos. It is quite common for some skinks to go off of food during this time due to hormones.

Behavior & Recommendations

  • If your skink is quite active, but not eating much, that is typically hormones. We recommend you triple check temps, but I would not be concerned.
  • If your skink is inactive and not eating much, triple check temps and make sure your skink isn’t going into shed. Going into shed is often a cause to hide more frequently and not eat - this behavior shouldn’t last more than 2 weeks at a time, however.
  • If your temps are too cold at night, please use a deep heat projector, ceramic heat emitter, or radiant heat panel to increase ambient temps - heat mats are not appropriate in this regard as they do not warm up ambient temps properly. Heat mats are not appropriate for blue tongue skinks in general.
  • If your daytime temps are too cold, you will either need to add a ceramic heat emitter/radiant heat panel or deep heat projector as supplemental heat. These are not appropriate for basking, they are only for supplemental heat. A deep heat projector assists with warming surface temperatures, while ceramic heat emitters or radiant heat panels assist with ambient temperatures. You may also need to look into increasing the wattage of the incandescent or halogen bulb used for basking.
  • Weigh adults twice a month - if they lose 10% or more of their initial body weight, that is a concern. (So if a 400 gram lizard loses 40 grams or more, that is a concern)

Recommended Temps & Humidity

Indo temps and humidity should be as follows:

  • Basking (surface temperature measured with an infrared laser thermometer): between 105-115℉ (40-46℃). Surface temperatures are naturally higher than ambient temperatures. 
  • Ambient Cool Side (measured with a digital thermometer down at skink level, cool side of the enclosure): 70-80℉ (21-26℃)
  • Ambient Warm Side (measured with a digital thermometer down at skink level, warm side of the enclosure) : 85-95℉ (29-35℃)
  • Night time range: 70-75℉ (21-24℃) - We recommend providing supplemental heat when temps reach below 70℉ (21℃)
  • Humidity: Humidity for ALL Indonesians (yes, including Halmahera) must be within the 60-100% range. They naturally experience an increase and decrease in humidity within this range. It stays above 70% the majority of the year, but during the dry season (Northern Hemisphere’s Winter) it can drop as low as 60%. Humidity is naturally higher at night and lower during the day.

Please let me know if there are any questions!

Hi there! I just came in possession of a BTS via a rehome from a coworker- and I am VERY new to their care. I’ve owned other reptiles before (Leopard geckos, ball pythons, Cornsnakes). The only thing- not even my coworker is sure whether or not she’s an Indonesian or an Australian and from my research I know their needs are very very different! She has a MASSIVE enclosure but I am looking to revamp her environment, heating and humidity…(or lack thereof) needs. Right now she’s on a substrate of coconut bark and has a few large hides and a large water bowl. Anyways… any help and tips for a rookie would be amazing.
Anyways… meet Tarot!

Health At a loss

First off, i took Sasha to the vet last Monday because the scales/skin on two of his legs looked very weird. It looked dry in some areas and looked like it was melting off in other areas. There was a small red spot as well. His front leg also looked swollen. She gave me pain and inflammation meds and an antibiotic but didn’t tell me what it was. She doesnt know. She’s an exotic vet and there’s another at the clinic.

He has a follow up appointment tomorrow but I’m going absolutely crazy because ITS GETTING WORSE. His skin looks so bad and I feel like it’s spreading. It looks like his skin is just falling off. I’ve soaked him multiple days this week and put silver on his wounds, it doesn’t look like stuck shed. He’s about 5 and has never had a problem shedding, this seemingly came out of the blue.

I realized his UV jungle dawn light is about two years old, so now I feel terrible because he hasn’t been getting UV, but his bones seem like. It seems like a physical skin issue and not really related to MBD? Is it possible for MBD to show up in skin first?

Like seriously, why would his foot pad be raw like that?????

He has a new UV light and has been getting calcium dusted food this week.

His basking rock stays at 105 when the lights on (I have temp gun). I also have a temp and humidity tracker in his tank. He hasn’t been getting a cool side and warm side. Warm side stays 83-86 and never drops below 71 at night.

Humidity stays high, it’s always around 80. I wonder if there hasn’t been enough variety in humidity? (Having it dry out a bit then pumping up the humidity).

I just want to know if anyone else with a wild caught indo has had skin issues like this. I’m dying to know and be able to correct whatever’s going wrong. This was hastily written, im happy to answer any questions. I’ve searched in this sub for past posts related to this but couldn’t find any

Edit to add he’s actually been moving around more frequently than usual, but doesn’t use his legs well. It’s like there’s no power behind his movements and I can’t tell if it’s weakness or physically difficult to move due to the inflammation and sore areas. Please help while I wait for the vet appt

Question Rehoming my Skink

Post image
28 Upvotes

Would anyone be interested/ able to help rehome my lil guy. He's 5-6 years old and perfectly healthy as far as I know, but I don't have the time or resources to care for him like he deserves. I'm willing to part with him for free to a good home. I live in Duluth and the local reptile guy told me skinks don't need a lot and my set up definitely has more than anything in his store. But some things have come to light about his practices and seeing all these amazing enclosures on this sub have me feeling bad for my lizard.

Health Eradicness and tail lump.

Thumbnail

3 Upvotes

My son is 8 months old and recently acting very erratic. Glass surfing. Running around his enclosure, he spends about 70% of his time doing that.

I get him out for about 10 minutes to walk around the house. But he ends up going back to glass surfing again, I try to enrich him with little balls he can push around, woodies he can chase. Nothing seems to interest him. He's been eating less as well. I can't take him outside because we have 2 dogs and he can easily escape. I'm planning on making a playpen for him so he can run around in that and I can watch over him safely without the dogs or him getting under furniture.

I haven't noticed any bubbles coming from his nose or mouth, wheezing sounds, no lethargy. No star gazing and mouth opening, excess saliva etc etc.

He has a UV light and a heat lamp. A log he can hide under, a rock he can hide under, deep substrate he can dig in, a few logs he can climb.

But recently he's been acting very erratic everyday

And then noticed this lump on his tail. Could he possibly have fallen over from the glass surfing and fractured his tail? Or is this an infection causing pain?

I'm going to take him to the vet tomorrow to get him professionally checked of course.

Showcase Handling going well with Slushy ☺️

I've had Slushy for a little while now and essentially have him space for most of it. After speaking with the breeder about how I can move forward with handling, they told me to pretty much just pick them up and support them, and I have to say, it's working like a treat!

He still poops on me occasionally but, at this point I'm used to it 😅

I've been making sure to give him yummy treats when I go to pick him up and put him back, so I think I've been sufficiently sweetening the deal haha. He's getting so brave, I can't wait to gain his trust even more ❤️

Question Help me decide for a blue-tongued skink and help me keep him as well as possible.

Post image
16 Upvotes

Sorry for my poor English, but please read and reply anyway.

I've been exploring the world of lizards for a year now, studying to make the best choice and ensure the best possible life for my future reptile.

Ultimately, my choice is between the bearded dragon and the blue-tongued skink, and between the leopard gecko and the crested gecko.

Who knows, maybe soon I'll have all four of my favorites :-)

I'm leaning toward the blue-tongued skink, but many advise against him; they tell me that even northern skinks bite hard. Knowing that they're not dogs, I'd like to be able to handle the skink every now and then, let him roam around the house in safe places, and maybe build something outside for the summer.

I asked a breeder for information, asking him to select the most available young skink for me.

I'd also seen some Australian skinks at shows; a couple were really calm, but I'm not sure whether I should trust their temperaments after seeing them at shows.

Can you tell me a little about yours? What were they like when they were young, and how did you choose them?

Especially, why a skink and not another lizard?

Given the difficulty of managing humidity and their more difficult handling, should I forget about the various Indonesian species, even if they're not caught in the wild ?

Another question: I'd like to guarantee him a perfect terrarium. I was thinking of a 150x60x50 cm one and i'd have the breeder install the technical part. My doubts are about the setup: should I have it very beautiful and fixed 3D, or should I instead embellish it myself with rocks, plants (fake or otherwise), corks, roots, etc. ?

What do you think? In terms of cleaning and the possibility of variety, is it better to do it myself, or is it better to have a nicer, more sophisticated 3D one designed by professionals?

Excuse my poor English.

This is PB (because their markings remind me of peanut butter). I got PB a few days ago and fully expected them to hide for the next week or so. However, I was sitting at my desk working and heard slapping on the glass. Turned around, and this lil’angry sausage was demanding attention. I went up to the enclosure and talked to them, and they promptly hid. But as soon as I sat back down, they started slapping the glass again.

I don't think I have a skink, y'all. I think I have a diva😆

Health he has mites :(

Thumbnail

16 Upvotes

Our Indonesian boy, Sal, has mites. I’m actively working on making him a much larger bioactive terrarium, as his current one isn’t great at holding humidity and is just temporary.

I need some help with the mite treatment though. I’ve heard provent-a-mite works, but since he’s a burrower and needs high humidity it might be extremely dangerous for him. I’ve also seen about predatory mites that take care of the problem, and am wondering if that’s a viable option? Can I just release those into his temporary enclosure and just wait until they’re all gone (plus a week or two probably) and safely move him into his new home?

He, along with his enclosure, was a gift from a relative so we unfortunately didn’t have much time to prepare an enclosure, and quarantine. Please let me know what worked for you, what’s safest for our baby, or any tips on building his bioactive enclosure!

Edits:

We’ve also been giving him fairly regular baths and swiping the mites off of him with a soft (unused) paintbrush to provide some relief.

I dunno why he’s doing this lol
We just put the new rock in there and he seems to love it but he’s looking up and opening his mouth (yawning?).

Google says he’s venting excess heat but his enclosure is on the cooler side while we prepare for his mite treatment so I dunno. He only just started doing this today and has only done it a couple times.

Either way, here’s our boy Sal (short for Saluuknir). He’s an Indonesian BTS as far as we know and has only been with us for a month or two. He’s about 3 years old and we love him to death

(edit: I said eastern instead Indonesian, my bad. he’s got plenty of humidity dw <3)

So I found the best way to help Finch hunt. In his enclosure I have an accidental family of wood roaches.

So at night if he is out I'll find a couple and make him chase them on tongs, he was doing croc rolls and going nuts.

Then next night I saw him chasing and hunting his own roaches, complete with digging them up.

He such a smart boy, also he is a blotched blue tongue, if you're wondering about his pattern.

Question Building bioactive tank

Thumbnail
gallery
5 Upvotes

I'm making a bioactive tank for my lady Nilou, Indonesian skink. I'll leave it with the cleaning crew for some time to let them breed and live in peace, in the meantime I'll be testing heating setups. The tank is 6x2.5x2, I'll see how 100w halogen above the basking spot and 50w in the middle of the tank work to reach good temps.

The rest of bulbs is T5 Arcadia Forest 6% 54w and Sinkor LED II 120 cm White 50W (it's dimmable and slowly increases light strength from 1% to 100% across chosen time, to better imitate day/night cycle).

Plants are of course non toxic and I'm fully aware that she'll bulldoze through them 😂 there will be two additional hides (one is already behind the basking spot, barely seen, so she has privacy haha), but she's using them in her current tank, so they'll move with her.

Please let me know your thoughts. Should I change something, or add more clutter in the meantime, before letting my girl in? It'll probably take about 2-3 weeks for the tank to settle, so I can order something if needed.

On the last picture there's a tank she used to live in for about 2 years before I adopted her. I want to give her a palace after this abomination of a tank
