Just wondering if you guys would be able to help me figure out whats going on. My betta who normally looks like this (when swimming around or just after flaring):
He still swims around all of the time, but he keeps his fins clamped/stiff looking (really apparent with his bottom fin and tail fin). He still eats fine, still tries to flare when he sees his reflection, and all around is ACTING like a normal betta, just doesnt look like himself.
Water is at about 81 degrees, ammonia 0, nitrites 0, nitrates around 20 (before my recent water change, so should be lower now). He has plenty of plants to hide in and doesn't seem to be acting depressed or acting sporadic, just has his fins clamped. Any idea why?
A while ago i made a thread about noticing bettas having silver chins so:
In regards to the gray chin thing, it comes and goes all the time. I notice it more when hes just swimming around, just looks like a discoloration under his chin, goes away when he eats/gets excited. (had to edit the picture to try to bring out the chin, hence why it looks weird)
