Just looked in my Betta's tank and he now has some sort of fungus (?) growing on his tail and his top fin. Its black with white fluff around it an I'm kind of worried.
A few days agao I went to take him out of his tank so I could clean it and he got stuck in the net and breathed air for a few more seconds than he should. I put him back in his dirty tank and left him in the dark to calm down. I waited for a few days to clean the tank and when I put him back he seemed slow and hid from all movement, which is odd for him because as soon as something moves he's right there...I dont know if that has anything to do with whatever is growing on him or not. Also, he just sits there, moving nothing, not even his fins. I keep thinking he's dead but then when I try and poke him he moves away.
Awhile back I had thought he had tail rot but it turned out that he was just nibbling his tail. But now I've read about advanced tail rot and can't get it off my mind.
I dont want to see another one of my betta's die because so far I have lost two out of four...
