I added a Royal Gramma about a week ago to my 15 gallon tank. The tank has been up since October '17 and the other fish are two Oc. Clowns. The Gramma has been active and not hiding too much, but he does have a few spots he really likes. He has not eaten that much but I often see him picking at the rock and glass (I assume eating pods). My tank does not have that large of a pod population and I was wondering if it would be a good idea to seed the tank. I have about 20-22 lbs of LR, but no refugium or sump, just a pretty basic setup. I want to eventually wane the fish to pellets since I have to leave the tank on a vacation feeder semi-regularly as a college student. He has been eating frozen krill.
