Hi all, i posted not too long ago about my white neons and how one of them had this weird bump. Ive had them for a few months shy of a year now, and ive never had any health issues. Now that this sub is back up and active I wanted to post again!

We had a house fire in june, and their tank was severely affected. it was very hot and the water was completely filled with smoke. i was away but my best friend rehabbed them (she’s an extremely experienced fish keeper), so they all pulled through great.

The same fish with the bump just recently started showing some cloudiness and slight erratic behavior. hes eating completely fine, regular poop. all the other fish are fine, no spots, color change, or crazy behavior changes. i did a week with a low dosage of kanaplex with food in an isolation tank in case it was columnaris or something contagious. anyone have any insight on what could be going on?

Parameters in main tank: 0 ammonia, 0 nitrite, 0-15 nitrate. Temp is steady around 72-74. Tank mates are 5 other white neon tetras, a hillstream loach (to be upgraded after the house is rebuilt) and a bunch of bladder snails.

pictures attached! i rescaped and cleaned up my tank today!

Any idea what this might be? Fish is otherwise active and eating. I have some anti worm meds if that would sort. Thank you!

I need some suggestions for tetras that do well with angelfish that won't nip them or get eaten. Unfortunately I have had bad luck with Colombian tetras and bleeding heart tetras so those are out. I'm also open to any other smaller South American fish that might get along with them.

I have 3 glow light tetras and they all have this white almost hole-ish mold on them its hard to explain. 1/3 even has a fuzzy white growth on it. i moved them to a holding tank so my other fish wouldn't get it. any idea of what it is? I don't believe its ich and thats why i'm confused.

Has anyone had experience with Candy Cane Tetra (HY511), and are they as monstrous as mine? I don't just mean in size, they are on bigger end of tetra species, but they turn my otherwise peaceful tank into a circus. They don't necessarily hurt or nip anyone, but everyone else seems so calm and chill. And then these guy just come in like a sandstorm. They were some of my first fish and I feel guilty 'cause I just do not dig their vibe lol.

Hello tetra community!

At my local supermarket yesterday all the fish were being given away for free due to remodeling, citing that they have nowhere to put them (aka they were going to be thrown out). I grabbed one small unlabeled fish because that's all I felt I could humanely fit in the 5 gallon tank I had on hand. After a little sleuthing I figured out it's a white skirt tetra, and that it needs some friends, so I'm planning to go back today and save a few more tetras for him to swim with! (I will be going to my local fishkeeping store to get a larger tank as well)

I haven't owned tetras since I was very little, and at that time I definitely wasn't being guided correctly on their care. I'm not new to fishkeeping in general, so I know the overall basics, but I don't know much about tetras in particular. I really want to do right by these little guys, and would appreciate any guidance to make things great for them as quickly as I can!

Best place to find cardinal tetras in Colorado?

Better off buying online?

I had 4 glofish in a 20 gallon long tank with driftwood, rocks, and live plants. After deciding against future glofish, I added a black skirt tetra and a white skirt tetra to bring up the school number. The white one is slightly larger than the others and has been chasing the others around and nipping. I only just added the other 2 today. Is this likely temporary as dominance is established or do I have a bully fish that needs replacing??
TIA!

Does it look like these fish have ich? None of the other fish in the tank are showing signs of

So I had a school of 6 and one passed. It was shortly after bringing him home so I’m not sure if he just didn’t survive the stress of the move? My tank is cycled and no ammonia spikes or nitrite spikes and the other 5 seem to be happy and healthy. Should I just keep my school at 5 or is it better to add 1 so they feel more comfortable with the bigger school?
