Welcome and sorry to hear about your loss.
I was thinking about what to do with my tank once we go on a honeymoon. I can get the slow release food but as far as just general oversight, a thought had occurred to me.
What if, one of the days that someone was there to check (I wouldnt ask them to come every day but maybe two or three days out of a week), they found an aquarium in disarray? I don't know any other "serious" aquarists and wouldn't trust anybody to fix anything even if there was a major problem. Sure, they could plug things back in or attempt
to get the power back on if teh problem was as simple as that. If all that would be necessary is a circuit breaker being flipped then that is an easy fix, but for anything complicated, IMO
having someone to come and check it wouldn't really matter unless it was someone who you trusted that could fix the problem.
The only thing worse than coming home from a long vacation to a tank full of dead fish, would be knowing I had a tank full of dead fish while I still had a few days of vacation left.
