I'm soon to go on a 12 days vacation and want something to feed my 2 fishes for the duration with an auto feeder. I've read that it's ok to starve them up to 1 week, or maybe even 10 days, but I think it's kind of cruel and in my case it's longer.
One of my fish would gasp for air and get floaty after all kind of commercial foods, even just one pellet. I've tried saki-hikari, hikari lionhead, omega one, and some flakes. I have some anacharis in my tank right now and they don't seem to be interest much.
Obviously I can't put gel or fresh food in the auto feeder. So what do you guys recommend? I'm thinking maybe algea wafers?
My tank is a 29g. Two orandas around 3 - 3.5 inches head to tail. 400gph filtration. Some live plants that keep nitrate below 10ppm even after 1 week w/o water change.
And what auto feeder most reliable? I'm not too concern about the exact amount of feeding, but more about reliable performance, something that still function like it should be even after 1 week with no check-up, drying, or unclogging. My water level is filled pretty high to prolong evaporation and to prevent strong downpour that push my sand around, which means my glass top is always damp at every corner.
