This is my first time keeping a betta in some time, and I'm a little worried about his behavior. The fish in question is a blue and red male Crowntail (seen as my avatar) who is, at present, nameless. I've only had him for about a week, but he's become sort of listless lately. At first he was swimming around the tank a fair bit and his fins were flaring some after the first day or so I had him. Unfortunately, it was about at this point that there were some issues. His tank mate is a black mystery snail (I've had him about two weeks and his name is Hershel) who was, for lack of a better phrase, befouling the tank. I got a filter that worked on my second try (the first one was too big) and, about a day later, the water was clear. But it's started since a little before I've had this filter that the betta hasn't been doing too much. The snail's far more active now that the water is cleared up, but the betta is truly concerning me. He sits on the leaves of the Anubias I have or hides beneath it. He's made slight divots in the gravel that he'll lay in or he ducks behind the rather large rock that's also there. He used to be far more active than this... Plus, he hasn't been eating. I've heard that switching his food or breaking the pellets might help, but I'm truly not certain if I should be worried about his behavior or if I'm making a mountain out of a mole hill. A little help would be greatly appreciated.
