pyramid butterflyfish?

[Aquattro]

So I picked up a pair of these last night, so we'll see how they do. They're in my 90 for a couple of weeks, so if they develop a taste for acros, I can pull them when I transfer to the new tank. Originally there were three, but one went missing at the LFS, probably due to a large lobster in the same tank!
If these work out, I'll look for 3 more..
