:help:I think that two of my three fishies might have ich or something but I don't know. This morning I noticed a small light coloured mark on my betta's head. Then one of the dwarf platys has a larger white sort of patch on its back. They are not acting unusual but I am very concerned about the marks. I am attaching pictures of the two in question. Sorry they are not the best quality but hopefully they will help somebody to diagnose. The little orange guy is camera shy and the betta on the other hand is in my face all the time. What do you think this is, what causes it, and what treatment can I use? From what I've read is it Melafix that I would add? I'm going to Walmart and the fish lady there I spoke to last time has some big tanks of her own so can hopefully help me also. Thank you.
