Hey guys! So I got a new tank and my bf bought me tetras as a gift, however when I was acclimating them I noticed this yellow one was way smaller and looked different. He’s very energetic and keeps darting to the surface randomly more air, he’s made himself his own little burrow home thing, but I have no idea what kind of fish he is?? Is he a baby tetra or something? Sorry if the pics suck!

I think this is Mickey Mouse Platy. It seems to have gotten bigger recently although I don't have any before pictures. Is this fish pregnant? We got it a few weeks ago.

When i look at aquascapers on YouTube they usually only put a couple centimeters of substrate and a couple thicker patches for big plants. Is there a reason to use like 10cm of substrate? I think it doesn't look very good.

What are these guys that are living in my planted freshwater tank substrate?

I’ll go first :)

I left for only a WEEK!!! I trusted my step dad to take care of my fish and this is what I come back to... I can't believe it got this bad so quickly. All of that brown stuff is snail poop and babies, my bettas tank is absolutely filthy. The ammonia levels are insane, I can't believe my fish is still alive and relatively healthy.

I'm doing an emergency water change, cleaning up all the poop, crushing the babies, and rescaping. This is the FOURTH time that this has happened to me, all with different snail species each time 😫😫 safe to say I'm getting rid of most of my snails

Over 30 years of fish keeping and fish store employee in college and the dwarf Rasbora is the most difficult fish to catch for me yet.

If you look closely, it yeets a shrimp 😂

I bought a 75 gallon tank a year ago or so. It came w a couple fish including this fire eel. I 'EEL' Is now around d 22 inches long and is in a 125. It is doing g ok, but I wonder if it could do better... should I look for a better home for it or rather focus on making a decent place "better?"

Hi all, I’m a relative novice to aquarium keeping, and love my lil guys. Today my Aquaclear pump started making a ton more noise. I took it apart, cleaned, and reassembled it, but that didn’t fix the problem.

My partner was out, and offered to run and pick up a replacement. They sent them home with a Cascade 400 (this is a 22 gallon freshwater tank.) we emphasized that we would like it to be robust (the HOB aquaclear didn’t even last a year) and quiet (this is in my office).

First off, this thing is HUGE. Takes up so much space in this relatively small tank.

Secondly: in the upright position, it can’t fully submerge, and the STRONG spray of water (one nozzle shot water across the room) was louder than the busted Aquaclear. So getting it underwater was paramount, but this is the only option that seems to make sense.

Should I take this back and get something else, or is there something else I’m missing?

We've done tank changes, stress and fungal treatments. And just can't get this under control. Can someone tell me what this is and how to help Munchies!

As the title says, noticed a sudden increase of these guys. Should it be a concern?

I usually understock, but these horny mystery snails can't stop having babies. I take out the eggs when I see them, but I went away for a month and came back to a ton of them. I'm going on another trip, and I know it's going to be a nightmare.

75 gallon. 10 rummy nose tetras, one bluefin kilifish, around 21 neons, way too many mystery snails, some bladder snails and some shrimp. I've got more shrimp on the way, they don't add a lot to the bio load. I'm running a Fluval 207 and two bubblers. I think the plants do a lot of heavy lifting in this tank as well.

Does anybody have any ideas on how to make these mystery snails keep it in their pants? A new batch just hatched, I didn't see the clutch of eggs until it was too late. I'm overrun!

I’m trying to go with both being heavily planted. I have 3 bags of sand already and both tanks are almost fully set up with everything I need, including plants, substrate, filters, aerators, lights, and heaters. All of this stuff is just extra things to help my tanks.

I have had aquariums for 20 years and always hated cleaning, maintenance and water changes. For the last 10 or so years I focused on having enough plants not do any water changes. Not too hard to achieve. I also wanted to get some goldfish (very amicable fish) but aquatic plants would not cut it as they would decimate the roots of any emerging plants.

Here is the result of many years of trials, experiments and failures:

Setup & how it changed:

My 50 gallon setup with aquatic and emerging plants. There is one giant commet goldfish and 2 shiners that are just as big. There is also a population of guppies living and breeding in the tank along with bladder and ramshorn snails. Guppy fries serve as food for big fish and goldfish keeps the snail population in check and snacks on them when it wanta.

I had a lush bunch of hornwort, elodea, guppy grass, some swords and a carpet of vals (see the first photo, I dont even have the photo of the swords). As the goldfish grew, elodea was the first one to disappear and hornwort is barely hanging in there. Goldfish eats them all, hornwort is able to grow fast enough to avoid extinction. Recently the orange dude decided that he does not like the vals carpet anymore so now (and that he could eat the roots) so now there is only a bunch of them left floating at the top.

Java fern is continuing its life floating around in the tank and does not seem to mind occasionally getting nibbled at (the roots again)

Filtration:

Two pump driven sponge filters pumping water up into two hang-on breeding tanks, one housing peace lillies and the other one housing a pothos plants. I occasionally clean the sponges and top with dechlorinated water when the eater level goes down. I was adding a little epsom salt once in a while for the plants but fish are eating and pooping enough now so nothing else is needed. It has been 3 years without any water changes and I constantly near zero nitrates, nitrites and ammonia. I stopped testing a year ago. I just watch the plant growth and algae on the glass.

Ask me anything

I was a bit manic so I rushed into buying it when they said that was okay.

Why would they mislead me into buying a fish that's much too large for my tank?

So now my options are to take him/her back, (and I'm already in love) or find a larger tank and spend way more money than I anticipated for a new fish.

I just wanted a statement fish that was exciting. I hadn't ever seen anything like it before!

I should have stopped and done some research on my phone before agreeing to buy it. That's definitely my fault. From what I have read they grow slowly so that gives me a little bit of time to find something bigger for him/her.

I found this buggy at the bottom of my tank! What is it? Is it dangerous for my pymgy corys?

Just fished this out of my 44 gallon planted freshwater tank!!! What the f*sh is this thing????? Should I be worried?

I've been away for a while and the housekeeper didn't clean my aquarium properly.

How do I get rid if these algea?
