Bought a Betta about five days ago. My girlfriend and I chose the most energetic one we could find, and everything seemed to be going good until this morning when I found him stuck to the filter. I was running late, and assumed that maybe the fish had died. When I came home to remove the fish, I noticed that his gills were still moving. The fish is still alive, however, listless and very somber. At one point he even just sorta sank to the bottom. He is hanging out in the top corner of the tank now, and has been for an hour or so. We bought a small starter tank kit that included everything thing we would need, and have followed all directions since purchase, so I can't figure out what is going on. My mom suggested that maybe he is stressed from being in fluorescent light (the tank is in the kitchen), but I don't see how this is any different than the store we bought him at.
Help?!
