Hi , ive got a large (30cm) flowerhorn, hes recently started going downhill and has got cloudy eye and a white slime on his body. I have done a 50% water change and treated with furan 2, but hasent helped if anything has made it worse, and now i have just noticed some tiny parasite in the tank which are the same size a BBS. What is this?? and what would be the best way to cure this?? Thanks heaps
