I have a 125 gallon FOWLR tank with six fish; a foxface, 2 clowns, an engineer blenny, pajama cardinalfish & a scissortail goby. I'm going away early morning Friday, returning between lunch & dinner time on Sunday. If I have to I could get someone to feed the fish but would prefer not to. Do you think there's any problem leaving them for a couple of days without feeding? I know fish are supposed to handle it just fine, but I've never done that before.
