A pic of the entire setup would be helpful...and do you know the water parameters (pH, nitrates, nitrites, and especially ammonia).
What temp is the tank and how long have you had them?
Hi,
I don't know the pH, it's water from the tap that I leave to sit for around 5 days and then put it in the tank. The ammonia and nitrates/nitrites are 0. I've attached a picture of their set up. The tank is about 2 feet long by a foot deep with a pump that sprays the water onto the side of the tank so as not to disturb the water too much, and the water is 18C. I've had them about a year. Before me they were in a tank without a filter or anything and before that they lived in a laboratory.
Brain was fine and then one day I noticed he had white fuzzy stuff on his back, so I came on this website and loads of others and they suggested it was fungal, so I gave him a salt bath at the lowest salt concentration suggested and he went absolutely mental. He thrashed around, bit half his tail off, he was going upside down and looked like he was having a fit. I was so scared that I took him out after 2 minutes because I thought I'd killed him. But then he was fine, so I gave him a 10 minute salt bath and this time he just lay there without moving, and from then on he basically died
