Brilliant idea with the feeder option!!

Even something that only held 8 ounces of pellets would be extremely beneficial for somebody who's away from the cages for a couple days at a time.

Aquatic Ecosystems makes a demand feeder with a little thingie that the fish nudges to dispense food. If I recall, they were pretty inexpensive.

Very, very interesting.

Holding a redear sunfish is like running with scissors.
