Ill be gone for a week and was wondering if anyone recommended any feeders for the guppies. also, should I leave the filter (biowheel) on all the time or should I timer it like the lights? if I leave it on all the time will it suck up all the food? will my snails and algae eaters eat it all? I hate having to leave them :sad: but sending a 12g setup with someone else doesnt make much sense. (I will be sending my fry tank though... those are MY BABIES!)
