Well, I got a betta at the pet store about a month ago to brighten up my dorm room. He's been doing a good job at that. Today, though, all of a sudden, he won't eat. He used to eat like a little pig. I actually had to start feeding him a little less than I had been, because he was getting chubby. I've been feeding him three pellets of betta gold once a day. I cleaned out his bowl a couple days ago, and I thought the little plant in it was bothering him, becasue it was plastic, so I left it out. He started burrowing into the marbles, so I put the plant back in, and he seems a little happier. But, he still won't eat, and he's looking a bit pale. When I tried to feed him tonight, he took it like he was going to eat it, but then spit it back out and now is just swimming around looking at it. His water feels a little cool, but I haven't done anything different than when I first got him, and the first couple of weeks I had him he was flaring and making bubble nests. He's really starting to worry me a bit... I don't want my little Sakana to die. Can anyone tell me what's wrong, and/or how to help him?
