The Tribal Blenny is commonly referred to as the Dusky Blenny, Highfin Blenny, Black Blenny, and Brown Coral Blenny. The Tribal Blenny needs moderate care and is considered a good species for any experienced aquarist. The Tribal Blenny grows up to 4 inches and should be kept in a tank not less than 25 gallons. The Tribal Blenny is peaceful in nature, and should not be housed with aggressive or predatory fishes. Since it doesn?t bother any clam mantles, or sessile invertebrates present in the tank but may nip over the clam mantles and small polyps of stony corals, that is why it may be considered a good reef dweller but with caution. The Tribal Blenny should be kept in a tank which is sealed and covered, as it has the tendency to jump out of the aquarium. The Tribal Blenny is mainly found grazing over the algae that grows on rocks sides or in bottom of the tank. Therefore, it acts as a janitor fish, and helps in maintaining the tank clean and clear. The Tribal Blenny should be given a tank with plenty of hiding places or caves that provides a place to hide or retreat when stressed or frightened. The Tribal Blenny thrives well in a temperature range of 72-78 degrees Fahrenheit and pH of 8.1-8.4. The Tribal Blenny is a peaceful fish, and is safest to keep only one fish unless you have a true mated pair. The Tribal Blenny can feed on vegetable matter, blue green algae, blanched vegetables or prepared foods for herbivore fish.
