The Bicolor Blenny is also known as the Two-colored
Blenny. The Bicolor is so-named because the anterior half is blue to dull
brown, and the posterior half is dull orange. Males are generally larger than
females and experience a succession of color changes, including blue, when
breeding. These Blennies exhibit great personality in the aquarium.
Generally found amid crevices and rocks on the bottom of
its environment, the Bicolor Blenny needs a tank of at least 30 gallons with
scattered rocks for perching and hiding.
These fishes are normally peaceful tank members, but have
been known to pick at other blennies, smaller gobies and dartfish. They
normally make a good addition to reef aquariums, but use caution in smaller set
ups, or with smaller fleshy corals, as they have been know to pick at the
mantles of clams, and at fleshy large polyp stony corals when underfed. In
larger reef aquariums they rarely do damage to these corals or clams.
The diet of the Bicolor Blenny should include vegetable
matter, including frozen and dried foods containing marine and blue-green
algae. It will also feed on (and help control) algae growing in the aquarium.
