First, sorry if this is covered somewhere, I've read all the stickies and stuff :/
I rescued two crowntails a few days ago and the one was in bad shape when I got him home. Neither was healthy, but the other is doing good now. The sick one is in a 1.5 gallon tank/bowl, the water is a steady 78F, I do partial water changes daily (no filter) and treat his water with aquarium salt...and he was treated with BettaFix when I first got him home.
When I brought him home, though, I kinda thought maybe he had swim bladder issues. He's lethargic, clamped fins and swims normal, but floats slightly sideways or straight up and down when he stops :/ This has improved a bit since I got him...the first few days he literally sank and fought hard to reach the surface.
I'm not sure what color he's supposed to be, but he's got a white/clear body with silver fins, which I think is just a really faded blue :(
So...should I just wait it out? He's getting marginally better...or is there anything else I can try?
