Question about Butterfly Fish

[viperfish]

I had an Auriga, it was OK with pretty much everything but polyps such as Zoas, Palys, GSP, and it's favourite was Xenia. I was fortunate enough that I had a huge amount of Xenia so it grew faster that the fish could eat it. The problem with Butterflyfish is you just don't know what they are going to aquire a taste for. I think you would be pretty safe with leathers because of the awful taste (not that I've eaten them, LOL).
