Okay I have a friend with a new betta, a blue VT named Sudono
Now sadly she is keeping him in a small bowl, possibly half gallon, more likely a bit less...I've advised her to get at least a gallon if she can, with a heater since her room is cold. When I met him he was lying on the ground not moving much...so we floated a warm bottle and now she is doing daily 50% changes with warm water to keep him toasty and since then he's perked up.
However, the big problem is he has some white sort of fuzz around his gills which is slowly creeping towards his pectorals and anals, and he is too boyant, trying to keep his body down but his tail keeps pulling up. I forgot what this is? Shes treating him with betta revive right now for the white fuzz but while it seemed to help yesterday, the problem is worse this afternoon.
What is it and whats the treatment? f you have questions I'll get them from her asap.
