hikari gold and you can get some food for fish with reds for a treat. your fish will be looking good after about a month of the color food and some hikari
a varied diet is best. I feed several different types of pellets (floating, sinking and soft n moist krill) as well as frozen and freeze dried krill and bloodworms. I also try to add in some live every once in a while like live blackworms, earthworms etc. raw shrimp with shells are another great food that I feed sometimes to larger fish though cutting them up certainly works for smaller ones as well.
