I got my zebra danio about a month ago, and put him in my cycled tank (that had been running for about 1.5 months before that).
He lives with 2 other glofish (danios), and 2 guppies. I've been meaning to get 1 or 2 more danios for the tank, but I havnt had the chance.
Recently (as in yesterday) he hasnt been able to stay upright. He swims upside down basically. He tries to level himself, and ends up spinning. Before, he was exclusively at the top of the tank, but now he's hanging around the bottom.
I put some peas in, but all the other fish and snails attack it. I isolated him with some peas for him to eat, so he had a little bit. During the isolation I fed the rest of the fish, so he hasnt eaten in 2 days.
I only have a 1 gallon tank and this 10 gallon tank. pH levels show it to be slightly basic. Temperature is between 22-25 all day pretty much, but recently has been on the higher side, slipping to about 28-29 on occasion (I've been really sick too and havnt been doing the best job monitoring it). I also did a ~25% water change ,but that didnt help any.
Is there any chance for him? Should I put him alone in an unfiltered 1 gallon tank? Or is he better off in this one? Should I give him more peas or just put him to sleep?
