(Feel free to skip to the bolded part for the problem. :P )
I just rescued a betta last night from walmart. I was there buying toys for my corn snake and I happened to look at the fish, as I'd been considering getting a couple little fiddler crabs or something for a while now, and they had six of those little fish cups sitting out, and all but one of the bettas on display were dead.
The little guy looked alright, so I picked up a 1 gallon aquarium, some decorative stuff, betta flakes and water conditioner and brought him home with me. I've had bettas before as a kid, specifically one pretty steel blue that I had for at least a few years (can't remember exactly), so I know the basics and all. I figured if he made it through the week I'd go and get him a nicer home; it might sound kind of mean, but since his store-mates hadn't made it out of walmart alive I didn't want to get my hopes up.
Anyway, the problem.
He doesn't seem to be eating, and the tank water was murky after less than 24 hours.
I gave him about six hours before I tried feeding him (so he could get used to the tank, and because the walmart people had no idea when or if he'd been fed), and after waiting about 20 minutes for him to eat I skimmed the uneaten flakes off the top of the tank. Went to bed after that, and when I got up the water was pretty dirty; about what I'd expect after a few days.
I'm not sure what to look for to see if he's sick. I have a picture I took before I changed the water, and I could take another now if anyone might be able to spot something?
He does seem better than he did last night though, when in the cup and for a while after, he didn't want to move at all.
