Hey guys. We'll be going out of town for almost 10 days for Christmas. All 3 tanks (37g, 20L, and 5g) are pretty settled in, so I figured I would do a good 75% water change and vacuum job on them the night before we go. Also plan to plug the lights in through a timer. We have some good friends who are willing to come once a day to feed everyone. I totally trust them to come feed, but they don't have fish so its a shoot if they'd accidentally over feed. The fish will have to forgo their frozen food treats for the week, obviously a bit awkward to ask someone to thaw bloodworms and daphnia, then drip them in the tank with a straw... My question is, what are your experiences with having someone feed the fin-kids while you're gone? I see those weird vacation feeder things that you drop in, and have heard of putting flake food measured into those daily pill boxes, etc. Any advice?
