So, my a.c. went out and is out until Saturday. It's been out since Wed. I haven't seen any expired fish but am I right to assume to let them stay in the 88 degree water? They went from 74 degree but since it is summer in Oklahoma, the inside is about 10-20 degree difference than outside. I'm afraid to change the water parameters. What have you done? I have guppies, platies, ghost catfish, oto, and danios. Most are from Asia if not all.
