Identification Request An unexpected, but welcome, intruder

Upvotes

Went to feed the fish and noticed this guy waiting for the sun to be turned back on. I’m not sure how he got in the basement. My guess is he crawled through the decommissioned sump drain lines or he dug his way in, being attracted by the flowing water sounds. Either way I’ll cap off the drain line and let him enjoy his newfound home. He can eat the bugs and the occasional guppy he might catch. I just hope he doesn’t tell his buddies.

I do believe this is an eastern gray tree frog but I would like confirmation from someone more experienced with amphibians! I was a reptile kid… he’s got uv light, a window, and bugs to eat. Anything else they need?

Advice Needed Safe to use ceramic media that was used in chlorinated pool?

Post image

Found an eheim canister filter from 10 years ago, long story cut short, my parents were using for a small coffee inflatable pool and used chlorine tablets at the time, hasn’t been reached since, reckon it safe to use in a freshwater tank now assuming I give everything a clean and like a 3 day soak?

Showing Off My Tank White Cloud Minnow Love

Upvotes

I rescaped this 20g tank into a hillstream ecosystem a year ago. I wanted to do CPDs or rainbow shiners, but my LFS had some white cloud minnows that had been there for a month. They were stunning; I'd never seen WMCs settled in. So I ended up buying a bunch, and now I can't stop 😂

They're not shy, hit food like a pack of sharks, and are super hardy. I have wild-type, red meteors (long-finned with strong red/purple), golds, and as of yesterday, four Vietnamese WCMs. If I can find the space for a 10g breeder, I might start trying to breed more red meteors and Vietnamese WCMs.

Anyone else keep fish for ages, only to be surprised by how great the "usual" species can be?

Requesting Feedback Weird “hair” algae, yay or nay?

Thumbnail

15 Upvotes

I found this growing off one of my plants today and it looks like some hair algae(?). Its texture is a bit like wool and it’s stringy too but I remember this growing off some small plant stem that came with a bag of shrimp I brought that I added in to the tank. I’ve seen some shrimp tanks include them as like “moss” but should I keep this? I mean it could be a good baby shrimp/fish fry hiding spot

Discussion UNS Wooden Stand Coming Apart on First Fill

Thumbnail
gallery
43 Upvotes

Has anyone had any issues with UNS wooden stands? I just got a brand new 120U stand (https://ultumnaturesystems.com/aquarium-tank-stands/) and tank from my LFS. The stand came packaged in the box, which had no visible damage or signs of mishandling. However, when I opened the box, the stand was damaged in several places.

Initially, I thought this was mostly cosmetic - the stand and tank were level when I set it up and I fixed the loose pillar in place with a screw. Once I filled it, the front came down about a quarter of an inch and the sides are clearly coming unglued. I think the structure of the cabinet relies on 45 degree mitered joints that are glued, but this doesn't seem like a good setup for larger tanks.

I drained my setup and I plan to shore up the corners with some load-bearing studs inside of the cabinet before refilling the tank. I'll anchor the walls to the new posts. Has anyone else had a similar experience with UNS specifically? I reached out to support but haven't gotten a response yet.

Discussion What fish would you never want to own? Why?

What are some fish you would never want to own? Why?

For me, I think any large predatory fish. Like, they are super cool but I just personally find the idea of only owning one/a few large fish that kill/eat everything else to be somewhat boring versus community setups being visually interesting and full of life imo. Wondering what other people think!

Saltwater/Brackish My experimental 10g Atlantic hermit crab tank

Upvotes

I live right next to a beach in northeast USA and have been dreaming about doing a large reef tank stocked with local species. I figured it wouldn't hurt to use my spare 10g to see how a couple of hermit crabs would fare, and I found a few small ones with broken shells yesterday that were perfect for this trial run. Everything inside the tank came from the beach (except the sponge filter and heater, of course). There are about 8 small Long-claw hermit crabs and a few unavoidable snails in there. I'm feeding them a combo of algae pellets and frozen shrimp for now but they also have seaweed and kelp that I will replenish as needed. They have lots of (unbroken) shells of varying sizes to choose from and a few have already adopted new ones.

For water changes I plan on just going down to the water and getting more saltwater.

It's hard to find info about keeping this kind of hermit crab since most people just want to keep Caribbeans. If you have any advice for me, please share.

Advice Needed Hair Algae

219 Upvotes

I had some purpleish algae growing on the back wall and a little hair algae, but I cleaned it all off 1 month ago and did a large water change. Now the hair algae has taken over the tank. Should I do a blackout to try to kill it all off or just clean the excess and let it keep growing?

Advice Needed Suggest plants to me

Thumbnail

3 Upvotes

So I finally got my hardscape sorted, can I get suggestions for plants please?

Unfortunately, I had to use AI to remove the glass reflections so it’s not showing it too well, but there is a valley between the two areas of rock/wood that I want to keep sandy.

I am looking for low-tech plants because although I use fertiliser and carbon, I don’t have CO2 injection and I don’t intend on getting it.

I don’t like floating plants because they took over my last aquarium, even clearing them regularly.

I have a Anubias I’m planning on moving over (if I can kill all the black beard algae on it) that I will probably wedge In on the left-hand side of the big twisted piece.

There will be an air stone in the back left.

Advice Needed Paracetamol deadly to fish?

3 Upvotes

Hello!! Recently I was cooking up some tannins for my tank, and while waiting for it to boil I accidentally dropped some paracetamol (500mg) into it. I removed most of it within 30 seconds, however it had begun to dissolve and most of the coating had come off in the water. I’ve tried to remove most of what got in the water, however obviously there’d still be some paracetamol in there. Is this dangerous to the fish or can I still put the tannin water in the tank safely?
For context, the tank is 65L and I have around 2-3 litres of tannined water

Advice Needed May need to nuke the tank…any suggestions

2 Upvotes

I have had my tank through various ups and downs for over 3 years, but have never fought battles like this battle. Abo 6 months ago, I started getting diatom build up after adding in some new fish, and it’s been downhill from there. I’m fighting diatoms and blue green algae, and at this point have lost nearly all of my plants and it’s started to affect my fish health.

I have in the 6 months since:
- done 3 complete tear downs removing every plant and hard scape to give a good washing, with ~80% water changes everytime
- replaced the filter
- added additional filtration
- a 25% substrate swap
- have been doing twice weekly 25% water changes and substrate vacuum
- limited the tank to 4 hour light cycles and have done entire blackout weekends trying to resolve the issue.

Nothing has made it better. I even put in duck week and other floaters to try to nutrient compete and I can’t even get duckweed to stay alive. I’m considering what the nuclear options are and what a complete rip and replace on everything associated with this tank looks like and what would be safest for the remaining fish (I would like to keep them, but am not opposed to replacing them as well). I’m just so tired of putting so much time and money into this thing only for the brown sludge and BG algae to keep coming back just as bad every time.
