I don't want to hijack the thread. But maybe it's related. I had a runty one not eating awhile back. Temperature fixed it, turned it to 92 for awhile then settled at 90 for probably 10 days. All seemed well. Started creeping it down slow (degree every couple days), got to 87 and that fish plus another had slowed and eventually stopped eating. I've got it back up to 89 now, the bigger fish in the cohort don't seem to care at all what temp it is, they keep eating. One of the two seems to be eating more and the other is at least pecking at the filter and food occasionally.
So the question is, when you bump temp up to stimulate appetite... what's the end game? To slowly creep it back down? Find some middle ground? Is the idea that once they start eating they should keep eating once temps come down a bit?
