Help. I have a 190 litre tank with 8 Fancies, 2 Plecos & 15 White Cloud Minnows. My fancies vary in size. I have noticed over the past couple of days that my smallest, a Gold Fancy, has some blackening to the tips of its back fins and also to the base of it's body (only on the right, nothing appears to be on the left). I absolutely stumped as to what this might be, is it a fungus of some sort :?: If so, I'd better get to my fish shop tomorrow to get some meds :BIGhmm: All seems okay with all fish, including this one, no unusual behaviour and water quality is just great.
