NLS 10mm monster pellet when it comes out this month. I also feed market shrimp, tilapia fillets, smelt, white fish, silverfish, and whatever else is on sale at the asian grocery store near my house. Lately I've been making food cubes with added Ken's food pellets out of blended fish and gelatin. Oh yeah I also breed red worms and african nightcrawlers for my fish which they get three times a week. Once a week they get a live feeder treat.
