He is behaving a bit more like himself, he's active and hanging out at the top of the tank like he normally does. The only thing is he isn't eating like he normally does. He'll only eat 1 pellet at a time, I offer him another but he just ignores it. He will also some times take a freeze dried blood worm as well when he eats the one pellet. But this is not his normal appetite.
Also I believe he has either torn his fin or developed fin rot. I had him flare briefly for me (which I know is not an ideal thing to do when your betta is stressed) but his swimming and behavior has been a little off, he moves just fine, but it didn't seem like he would use his tail as much for swimming. And he would never spread it out like he usually would. But when I put a mirror against his tank, his top and bottom fin spread out, and he barely spread out his tail, which gave me enough of a view to see that there is a huge strip missing.
So I think tonight, after I go shopping I am going to get some epsom salts, and QT him and treat the fin rot, and hope this also helps with his stress and appetite. I'll do the 50% water changes every other day in this QT. And while that is going on, I'm probably going to remove the anubias from my tank. Since that seems to be the source of algae/possibly cyanobacteria.
Can anyone however tell me the amount per gallon of epsom salt to use for fin rot?
