I posted 6 days ago that my f. Platy had what looked like ich and the dwarf gourami had a red bump. They've been in quarantine with melafix for that time and the ich is gone. The gourami's bump is gone with just a little redness left. Today, he's lethargic, sometimes resting on the bottom, though he is eating. Should I move them back to their tank? And do I need to acclimate them since they've been in the medicated water? Before and current pics below.
