Mobile Bay Reef Keepers

Could someone please tell me if these are herbivores or carnivores? These just showed up in our tank and I need to know if they'll eat our fish, corals or what:



Oh and it looks like something took over one of the Hippo Tangs...



And look, they even got to the birds!

I started a thread on another board and someone "adjusted" all my photo's with pink bunny slippers......

That is just too damn funny

lol
