Twice a day, in the morning while I'm getting ready for work, and in the evening after I get home. I feel NLS and Hikari pellets (only one hikari). Every couple of days I break a Hikari algae wafer into a few pieces and throw that in as well. Twice a week I will alternate one of the meals with either brine shrimp or bloodworms.
I feed 4-6 times daily, but in small amounts. Downside, if you can call it that, my fish have grown rapidly and do not stop spawning. I also do 30-40% water changes almost daily.
