As with all blennies, they need well established tanks with a LOT of algae. A constant supply. And the best thing to do is to make sure it will eat prepared foods before you get it. That's hard to do if they have to order one for you.
Else, they are a good canditiate for your tank, so long as you an provide them lots of natural algae to eat. If your tank is relatively algae free, it may not be the best choice. But, it may take to algae sheets like a cow takes to grass, and you'll have no problems. Something you can't predict, you know?
I lost an algae blenny to starvation...and I thought I'd be able to provide it enough food. It ate and ate and ate and it was still not enough for it.
