Hi, Will someone please tell me what this is?
Dark blue, yellow bands.
Came in on live rock about 1 year ago, was about 1" long.
Now he/she is about 6-8" long. it moves a lot of my crushed coral
mainly from one side of the tank to the other. Now the rock work is shifting
and I'm tired of fixing it.
All softies, 2 true percula clowns, 1 target goby, and this guy....
Thankx

Right, it is not a goby, blenny or anything similar. It is Pholidichthys leucotaenia and is the only one of two fish in the entire family.
