The Bicolor Blenny is also known as the Two-colored Blenny. The Bicolor is so-named due to its being half a dull orange and half a dull brown, divided vertically. Males are generally larger than females and experience a succession of color changes, including blue, when breeding. Generally found amid crevices and rocks on the bottom of its environment, opinions are mixed as to whether the Bicolor Blenny is a peaceful tank member and safe for invertebrates.
Some believe the Bicolor Blenny is not safe with other species members and may pick on gobies and firefish. Others say the Bicolor Blenny is a peaceful community fish. Some say the Bicolor Blenny is safe around invertebrates and other sources say it will eat them. The best alternative is probably to combine these groups cautiously. The Bicolor Blenny needs a tank of at least 25 gallons with scattered rocks for perching and hiding. A diet of vegetable matter, including frozen and dried foods containing marine and blue-green algae are requisite for the Bicolor Blenny to thrive

The Scooter Blenny is also known as Scooter Dragonet, or Ocellated Dragonet. It has a mottled brown and white body with red highlights. The male usually has brighter colors and a larger first dorsal fin. A 20 gallon or larger reef aquarium that has live sand substrate, docile inhabitants, and lots of live rock is the ideal aquarium.
More than one of its species may be kept and it is best to introduce them all to the tank at the same time. The ratio should be 2 or 3 females per male. A 55 gallon or larger aquarium is required if more than one male is to be kept. It may be a difficult fish to keep due to its feeding habits. The Scooter Blenny will sift through the sand for food. Finely cut meaty foods and vitamin-enriched brine shrimp may be acceptable substitutes.
