I've had my male betta for almost 2 months now and its been living in a very small (less than one gallon) tank. About a month ago, he started losing color and turning white under his mouth and around his gills [see attached picture if you want]. His face is losing it's lustre and is just a dark, flat color. Also, the fins on his bottom side in the middle that are long and thin are shriveled up and white at the ends. His back and top fins aren't as full as they used to be, they're scraggly and unhealthy looking.
He's also acting weird. Most of the time, he sits there for hours with his nose in the corner of the tank and doesn't move. He blows bubbles there, which I know is a mating thing. When he swims, he bolts around the tank frantically. He seems to have lost his appetite also.
I have been using BettaFix remedy which is supposed to heal fins and restore color, but it's not working.
If anyone knows why this is happening or can give advice on how to make him better, that would be great!
Also, I was thinking about putting him in an aquarium that has 4 fancy goldfish (orandas and ryukins) living in it already because it has a regulated temperature and more oxygen in the water...would that be bad?
