the other morning i noticed what looked like ick on the goldfish(they're common feeder fish) and started treating them with aqui-sol and they didn't respond to that so i started treating them with matacyn-2(i know i spelled that wrong) and they don't seem to be responding to that either.

whatever it is they have started out looking like ick(just on the fins) and now they are covered with it and it's not fuzzy like body rot. looks like ick all over them. Anyone have any idea what it might be?
