|The bicolor blenny or Ecsenius
belongs to the family Blenniidae.
A common trait shared by all the members of this family are
the tiny appendages on the tops of their heads called cirri. Bennies
are endemic to the Indian Ocean and western and central regions of the
bennies have a
slender, elongated body with a dark purple
anterior and a yellow or orange posterior. They also have a rather
rounded head with a flat forehead and bulbous eyes. The blenny is
commonly confused with the goby family. Both are slender bodied smaller
fish with a bright color palette. Blennies have a single continuous
dorsal fin that runs the entire length of their body. Where as gobies
have a dorsal and a pelvic fin running parallel to their spinal column.
inhabit tidal pools where the water is
warm and shallow. They are incredibly good jumpers.
They will jump from
one tidal pool to another in search of food. This activity has earned
them the name Rock Skipper in the Indian language.

fish. Avoid mixing them with more aggressive species. Blennies are
shallow water bottom dwellers. They do not take kindly to the presence
of other bottom dwellers and tend to become territorial. Decide what
your preferred species in bottom dwellers is. If the answer is a blenny
then do not buy other bottom dwellers for your tank. A male and a
female may successfully be kept together. You will want to provide them
plenty of hiding spots. Blennies like to play peak-a-boo. They will
spend a lot of their day with their bodies sheltered in hiding places
and their heads sticking out from their sanctuary. Blennies are
specifically good for reef aquariums. The will graze on algae helping
to eliminate cleaning and maintenance problems. They have blunt heads
and combed teeth which is the perfect combination for scraping algae of
the surface of rocks.
herbivores. They will eat dried and frozen
fish food formulated for marine herbivores. It should be noted: Live
algae are an essential part of their diet. If you do not have algae
growing in your tank they may very well die. This algae growth does not
have to be prominent enough to be seen by the naked eye. It can be
microscopic in its presence. Generally there are microscopic amounts of
algae growth in water anyway. But I though it important to mention
because of the importance it plays in the blenny’s

caught for the aquarium trade.
It is not easy
distinguish a male from a female blenny. Males
are typically a little larger. They also tend to be just a little more
colorful. The color becomes more intense when they are in their
spawning cycle. Unfortunately Blennies rarely breed in captivity.
