glofish tetra

Hello, I have dozens of widow tetras in my 20ltr tank, which I bought a week ago. The fish were good night but when I saw them in the morning one of them got blood on its scales. I had already lost one fish a day ago. I don't know whether it is a coincidence or not but the died fish and the one...

My pink glofish tetra has developed this weird bulb on their fin not too long ago, and from looking it up and testing my tank (PH, Ammonia, Nitrate, and Nitrite, which all came out normal/nonexistent — I’ve had this tank for a few years now), I assumed it was too much oxygen. I had been letting...

Hi There - Brand new to fishkeeping and have read a lot online. So I think I know where I went wrong, but need to confirm before I make the same mistake again. We started fishkeeping last spring when my daughter’s 1st grade teacher asked us to keep the classroom goldfish over the summer. The...

Hi! I have always had a love for aquariums since childhood. My family kept a big one in our living room (150 gallons I think don’t quote me lol) I now have 2 aquariums myself but I’m still relatively new to caring for my fish on my own (thanks COVID 19 😂) everything has been going well but I now...

I absolutely hate to think this but I honestly don’t know what else to do anymore besides just start over. I’ve made a lot of mistakes and really think they’re suffering for it and at this point, I don’t know what to do anymore. My only main problem rn is that I just don’t know how to go about...

Hey everyone, So I have a 23 gallon Fluval fis tank. I have 2 mollies, 5 guppies and 6 glofish . My glofish are 2 pinks, 1 green, 2 purple and 1 yellow. The yellow glofish is my favorite I’ve had him since I started my tank almost a year ago. Anyway my light pink glofish hates my yellow...

Okay, so I’ve had a small 5 gal with glofish for years, and I upgraded to a 15 not too long ago. Maybe a month ish? I let it sit with plants and filter for a while before acclimating the 4 glo tetras I had into it (plus some snails), and about a week ago I got another tetra and 5 cory cats. I...

Good Morning Everyone!! I am new here, I’m hoping someone will be able to help me figure out what is going on with my Glofish Tetra. Having trouble swimming, staying near the surface swimming vertically or with nose pointing up. Overall just swimming strange. Only fish with these symptoms. About...

Hi im new to fish keeping. I have a glofish tetra who constantly opens and closes his mouth. Im not sure if its just a recent thing or it was like that when i got him around 3 weeks ago. Im freshly new and trying to be as informed as possible hes is the only one doing this. Also ever since i...

One of my daughters glow fish has what appears to be a small raised bump on its bottom fin. It’s the same color as the fish. It seems to be eating normally and the last water change was almost a month ago. The other two fish do not have a bump. It’s kinda hard to tell since I can’t get a good...

I cycled my 10 gallon (https://www.petco.com/shop/en/petcostore/product/glofish-glass-aquarium-kit-10-gallon) tank for about 3/4 weeks and saw the spikes of nitrites and ammonia then both hit 0 and the nitrates were at a pretty good level. From what I had read, it seemed like the whole cycle was...
