if you are going to be gone for only 4 days or so ;don't bother feeding them..
just do a 40% waterchange and let them be...they can actually go a couple of weeks without eating..

 

and sometimes even if I'm home, I'll not feed my fish for a day so their digestive systems can catch up.

 

yeah i skip feedings every now and then also.

 

Ok, i'm back. Hey everyone, how the weekend went well?

I can report back that after 3 days of catching fish, we caught no fish, so we decided to come home early. Damn, must be because it's winter or something, o well.
