So mine came in this morning from liveaquaria. I've been wanting one for a while, and when I got the email notice I ordered. I've had some pretty crappy algae issues in my tank - cyno and green hair as well as in three hours after scraping, I get the "dusting" on the glass. Cue the Jester. He came in a little on the thin side. Emaciated is probably a better word to use. Once he was acclimated, he was out mowing the lawn. He single handily devoured ALL the red cyno on the sand. Hair algae? Gone. After 12 hours in the tank, he's got a belly full of algae! He wouldn't touch live brine shrimp, no matter the size. (The bicolor on the other hand, ate so much he couldn't fit into his bolt hole in the live rock!) So if you've got a small reef tank check these guys out. Mine was swimming out in the tank from the get go, munching algae all the time.
