So, quick update, it's all like it never happened - I've had him under close observation for 5 days and he seems 100% normal, so I've put him back in his home tank.
I'm still a bit uneasy, but from what I read on here sometimes an RI can be
cleared up just by an increase in temps, right? It is a very warm week at the beginning of our summer right now, so maybe it just hit the sweet spot? Who knows.
Still not totally happy, but am going to try feeding him this weekend and see how it goes.
Thanks for helping me talk it out!
