I have gone 3 days without feeding my fish while I was out of town. I have a yellow tang, sixline wrasse, and a clown. The wrasse and the tang can find stuff to eat on their own but I dont think the clown has that ability (not sure). I plan on leaving for a 5 day mini vacation and was wondering if my fish would be OK without me feeding them for 5 days. I'll be feeding on a friday morning and wont be back until that tuesday at around noon. So technically 4.5 days.
