Right now, it's mainly Mazuri Aquatic gel diet. I love that stuff. I've also been doing some chopped capelin, smelt, shrimp, mysis, and bloodworms from time to time. With all the animals in there, it will require getting in the water to feed (this insures the bottom dwellers are all getting some). Earthworms will be added to the mix once the rays get moved over.dougefresh;702412; said:just curious, what is the diet of this tank gonna be? and how often will you feed?
