I foolishly bought one a long time ago and my angel died because it kept nipping its fins! They're also very, very fussy eaters! Bloodworms and brine shrimp is recommended. Also the snails that normally hitchhike on plants won't stand a chance with them.

But a lot of places sell them. Just look around at any LFS, I'm sure you'll find them. They're pretty common. But a word of caution, though, read up on their requirements and care BEFORE buying. Actually, this refers to ANY fish you decide on buying. I made the mistake of not reading up before buying and lost an angel to the puffer and then the puffer died because he just flat-out refused to eat the fish pellets.
