Hey guys. I just bought a betta fish for the first time, Fishmael, a few days ago. I like him a lot, but it's been quite since I got him. I can be sort of a hypochondriac (I guess especially with fish), but I've been a big fan of the forums on this site and all the helpful answers people give. So I decided to sign up and ask a question that I haven't heard an answer to.
So it's pretty late at night, I checked on Fish and he seems to be breathing pretty heavily. When I shined a bright light on his gills (which seem to pulsate a lot now) they were black with some red in the middle. I'm not sure if any of this is normal, or if the gills are inflamed/how to go about treating it or it's something else entirely.
Anything helps, thanks.
