He feeds a variety of bloodworms, cichlid pellets and kelp flakes. We watched some videos on YouTube and one was a sheet of seawead being devoured! It was crazy. So we got looking into it, Petsmart had the kelp flakes we bought. It was by the salt water sand and such. But they had seawead sheets there as well. We just thought the flakes were better for our tank.
The cichlids eat up either of those three like crazy. (Me) also suggested glass worms, which you can buy in frozen cubes at Petsmart. We just weren't going to make it home before they melted and had to be refrozen so we opted for the flakes this time around.
