I know that most Butterfly Fish are not reef safe but I heard that the Masked Heniochus for the most part is. My question is this. Will the Heniochus it eat a BTA. I have the opportunity to purchase one (Heniochus) at a fantastic price and was going to put it in my mostly FOWLR 125g tank, but I have one beautiful Red Foot Toxic Green BTA in that tank and don't want it eaten. Will the Heniochus eat this BTA?
