100% agree. I have felt the same way as sponge is a normal part of their diet. I knew ocean nutrition angel formula has some sponge and just cane across the panta rhei food the other day. I try to find always what is in their natural diet and make sure they get some of that. Like with my triggers I try to get them some urchin as well. Big fan of NLS for the convenience of a pellet. Working on a big build now that I would like some big angels. Conditioning a juvenile Emporer right now. Want to complete the group with a Queen, annularis and either a French, Grey or Cortez.
