Note from Penny:  Blennies are by far one of the most adorable reef safe fish offered in the hobby!  When they get to know their new family they aren't shy at all & often times will be right in view so you don't forget them.  They have a unique ability to turn their heads like a human which makes them seem almost human sometimes!  They love to sit on corals like personal recliners or on the feeder, to be sure you know they're hungry!  Though many are noted as "Algae" Blennies, please do not buy them to try & remedy an algae problem.  They are so little they won't make a true difference.  Fix what's causing the algae, which is probably creating a poor water quality condition as well & buy the Blenny because they're so cute, you just gotta have one!!  Heads up, Blennies can be intolerant to other Blennies in the same tank.  Introducing more than one at the same time or in very large reef tanks (100 gallons +) with lots of rocks might increase the chances of success.
