How long can fish really go without food? I'm leaving on wednesday to go home and I won't be back until sunday morning. Will it be alright to just feed them on wednesday afternoon before I head out?
what kind of fish? most will be okay. depending on what kind of fish you have, you could get one of those daily feeders that drop a portion in at time intervals, or those feeder cubes.
in that case, i wouldn't worry about it. feed them wednesday before you go and on sunday when you get back. they'll be fine. most fish can got a couple of day without food, no problem.
