I have a 72 gallon bow front with the glass lids I have fish and coral. MY coral can go a couple of days if I feed phytoplanton. I am looking for an automatic feeder for my fish that I can put in my aquarium without cutting my lid. Is there any feeder that attaches inside the aquarium for flake or any other marine food? I just want something for 3-5 days when I go out of town. IT can be battery or electric. I would not mind a chute for the food to go into the tank, but know that this would get wet over time, I just don't want a large gap in my lid for escape artists to get out of along with water loss.
