Hailing from the Family, Blenniidae, and also known as Comb tooth Blennys, Blennys are small sized, scale less Fish. Quite a preferred pick by aquarists due to their vibrant colors, Blennys are available in both, Marine as well as Freshwater varieties. Fresh Marine offers several beautiful Blennys of different types, to grace your aquarium. However, prior to delving into specific models, let us understand the following standards common to Blennys.

Compatibility: Blennys are peaceful and are generally compatible with the other tank mates, though some species are not too easy in Reef Aquariums. In addition, Blennys are territorial in disposition, and may attack the members of their own species, except for the ones they can form a mating pair with.
  • Habit & Habitat. Blennys are found in Tropical and Subtropical Waters of the Atlantic, Pacific, and Indian Oceans. These fish can be spotted on rocky coasts, Coastal Lagoons, in the holes between the rocks or reefs, near the sea floor, buried in sand, and empty Mollusk Shells. Adult Blennys may live in small groups or may prefer to stay solitary, while the Juveniles usually stay in Mangrove/Brackish water.
  • Morphology. Growing to a maximum of 3.9”-6.0”, Blennys have a slim and elongated body with prominent eyes and mouth. The Dorsal Fins of Blennys are long, and the Pelvic Fins are short and slender & precede the Pectoral Fins, while the Caudal or the Tail Fin is usually round. The heads of Blennys are blunt and sport Cirri, a type of Whisker. The distinguishing feature of these Blennys is their comb shaped teeth and therefore the name, Comb Tooth Blenny.
  • Ideal Marine Aquarium Environment. Blennys grow well in an aquarium with a temperature range of 72-78°F; Specific Gravity of 1.020-1.025; pH level of water within 8.1-8.4; and dKH 8-12. A minimum of 20 Gallons capacity tank is required for keeping Blennys. Ensure that your tank has ample hiding places (Rocks & Caves) for Blennys.
  • Aquarium Feeding. Blennys are Omnivorous and feed especially on Crustaceans, Mollusks, Mysis Shrimp, Brine Shrimp, Plankton, other invertebrates, Algae (especially Blue-Green), and Vegetables. Therefore, they sustain well in an aquarium with Live Rocks, which have ample Algal growth for consumption. They can also eat Brine Shrimp and Bloodworms, but vegetables are an integral part of their diet.
  • Aquarium Breeding. Male Blennys are larger than their female counterparts and their color changes when breeding. Aquarium breeding in Blennys is very difficult.
  • Care. Anybody from moderately expert to proficient can maintain Blennys. However, it is important to note that these fish are usually aggressive towards each other. Therefore, try increasing their number only if you have a well-established aquarium of over 55 gallons capacity. Keep 2-3 females per male.
