That seems kinda well...not nice. Just get an auto feeder and put some pellets in it. You should try to feed pellets anyways as they are pretty good for fish. But either way it gives them something over the time you are away.
I got an eheim auto feeder so my fish eat four times a day I like to keep them well fed I bought them I'm gonna take care of them and feed them I already put them in a glass box jmo
this is not true for all fish. many anthias and a moorish idol going without for 4 days can and will lead to their death. every fish has a different eating habbit. it is important you understand those habbits and feed accordingly. i would recommend an auto feeder as well. a fish that goes 4 days without food will be more suseptable to disease, and you could come back to a very sick tank.
hello again, just want to let you guys know that everything was fine. i had a fish sitter come by and feed them. i'm thinking about getting an auto feeder.
