I've had a pair of endlers for about a 2 weeks now, but all of a sudden, the female got this little white spot on her! At first I figured it was just a loose scale or something, but now she has 3 more, at least! I think it may be body fungus, but if so, should I treat the entire tank, or just the one fish? Mind you, this tank has snails and plants in it as well, so should I take them out first? Would they be ok, you know, not carry the disease out of the tank then back in? Or would they be able to survive the treatment? Please help! Thanks!
