My crowntail has developed a swollen abdomin in the last couple of days. It looks like he swallowed a pea whole, doesn't look like a pinecone tho like the other post. He's swimming like he's drunk & hanging out at the bottom of his tank. I moved him recently from a community tank, he was with some guppies & a cory & I had a female in a floating basket (removed her, she turned out to be an escape artist & very agressive, chewed the spikes off his fins & put a couple holes in them). He didn't mind the guppies, but they minded him, so I moved him into a 3 gal tank by himself. Shortly after the move he turned REALLY bad, he'd lay at the bottom of the tank on his side or with his tail straight up & nose in the gravel, unresponsive til I tried to remove him with a net since I thought he was dead. I started changing about 1/3 of his water daily, adding declorinater & salt, I gave him 1 pelt every other day, no clue if he was eating it or not. after about a week he was still at the bottom, but holding himself level & upright, still not very interested in eating. It's now been about 2 weeks and he's still hanging out at the bottom mostly, but he swims around and begs for food when he sees me & starting to regrow his fins. I feed him 3-4 pellets 1-2 times a day, and over the weekend his belly's swollen up. I don't have a pic right now, I'm at work, but there's no fuzzies, strings, raised scales, or sores that I can see. I can't tell if he's red any where, he's a red & pink betta. The petstore's only idea was dropsy and I'd looked it up before, I had a problem with another fish, and he looks nothing like those pics. I tried to feed him a pea thinking maybe he's constipated, but it sank & he's oblivious to it being in his tank. Any ideas?
