Hi, my neons and cardinals aren't looking too well. One has a large white almost blister looking spot on his side along with a white ball on his mouth, another has specks of white and another also has a white ball on his mouth. I only have 4 left now and none are looking particularly healthy. I have used primafix for a week twice and interpret anti fungus and fin rot along with lots of cleaning and 25% water changes but this hasnt worked. The other tank mates are all healthy and no white at all. (1 pearl gourami, 2 loaches, 2 catfish, 2 guppies and 3 amano shrimp) I did loose a pearl gourami a couple of weeks ago with a nasty looking skin problem. The neons/cardinals are eating and behaving like normal. I'm totally lost as to what to try next. I'm low on stock at the mo and don't want to top up until this has been cured. It is a mature tank that's been up and running for around 4/5 years. This is the first problem I've had any help would be grately appreciated!
First 2 pics are of the worst one.
