I'm a first time betta owner. My roommate and I bought Ghandi about 5 days ago, he is a blue and pink/red halfmoon betta, very pretty. He hasn't eaten since he's been home though except for one very small pellet the first day and nothing since. He has started to lose a lot of his color as well. Sometimes it comes back, but goes away again. He doesn't move at all, but rather sits at the top of the bowl motionless and barely reacts to anything. Also, these two fin sort of things are hanging down under I guess what one might call his chin area (sorry I don't know the technical terms).
He's in a 1.5 gallon tank, and we conditioned the water and checked the temp before we put him in. Both my roommate and I have never had a betta before, so we don't know what kind of behavior is normal, but our friends who have them haven't had these problems. I'm just worried 'cause he won't eat, is lethargic, and is very pale.
Any help would be great!
