My veiltail betta fish, Deadpool, has been acting quite weird in the past couple days. It's almost as if he seems like he's under the weather. He doesn't move around as much as he usually does. And he's always hanging up on top of the tank between the filter and he heater. He used to do that occasionally, but now he's up there like all the time. And he has a weird looking thing on his bottom fin. Idk like if it's like a tiny white spot, or a hole. I can't tell.
idk really about ph levels in my tank or any of that kind of stuff :(
