Recently I adopted a male half-moon betta fish from someone who was too busy to care for him. I'm very nearly a first-time betta owner (had one betta when I was little), so I've never really seen a sick betta, but after looking at some pictures and reading some stories, I'm worried about the little guy.
It looks like the tips of some of his tail fins are a bit ragged and maybe a little whitish. His pectoral fins are kind of tattered looking, and little white tips along the veins are sticking out. I don't see anything extremely bad and I'm not sure what he came like.
Then it also looks like he's bloated. His stomach's protruding, but I'm not sure if it's because of his previous feeding schedule (2 times a day) or possibly something else. He's not pine-coning or anything.
I'm also a little worried about clamped fins because his dorsal fin is usually down and he only raises it when stressed; I'm not sure if that's okay or not...
He's currently in the fish bowl his previous owner had him in because I'm still trying to cycle his future one. I decided to take him in now because I was concerned about the condition of his water and because he doesn't have a heater and it's getting cold at night (my friend's roommate doesn't like to have the heater on).
I've attached some pictures. They're a bit blurry, but it's the best I can do. Is he fine and I'm overreacting? Does he look like he might be sick with some of the aforementioned ailments? If so, what should I get to treat him? I am a college student on a budget and with only access to Walmart and no pet stores nearby...
Thanks in advance for help!
