I have a peacock goby, in a freshwater tank. My goby has a white lump (looks like cotton fungus) next to its gill, This is the second time its happened, my previous gobies developed this condition and one of them died within 6 hours of buying it, the other died the next day back in the shop as i took it back. Are they prone to this problem or am i doing something wrong?? should i have salt in the tank for the goby or not??
cheers!!
