I have tried every type of urchin (long spine, pencil, short spine, royal/pin cushion), trochus snails, turbo snails (zebra, Mexican, margarita), emerald crabs, all manner of hermits, extreme nutrient export (biopellets + GFO, chemipure blue), zapping it with an aiptasia wand, smothering it with epoxy and superglue (grows back through it lol), pouring hydrogen perioxide on it, and raising magnesium to 2400 with Kent tech M. This stuff is hell on earth I tell ya. I have yet to try rabbitfish or Tangs but I would expect them to find it unpalatable.
Let me know if the chitons work and where ya got them from. Really don't want to dismantle this beautiful custom rockwork with extensive carbon fiber rod reinforcment if I don't have to... Haha
