Fish Laying on His Side, Fins Out, Tinted From Blue to Red
So I've been posting previously about my fish, Zeke, on this thread. I moved him into a new tank after he took up tailbiting, but he hasn't really been recovering. Mostly been resting on his side at the bottom of the tank, changing places every now and then.
I think he's been eating, but I've only actually seen him flit up to get food once or twice, and not in the past couple weeks.
I've been checking my water chemical balance regularly, and none of the tests have showed any concerning levels.
Now he's at the bottom of the tank, still, on his side with fins extended, making no visible movement, and he didn't react when I moved the decorations around him to get a better look. Stranger yet, he appears to have turned a reddish hue from his original blue. He hasn't moved from that spot in over a day, so I'm worried he may have died. But his condition seems to be critical, and I didn't want to push or stress him any more if he's still there.
There have been a fair deal of cloudy things at the bottom of the tank. I presume from the food he hadn't been eating - though I have been giving him much smaller portions.
I frankly don't know what to do. He might already be gone. If he isn't I don't know what's affecting him...I suppose the best I can hope for is to wait and see, but maybe I can get some more advice on this...
