The Horned Blenny, Paraclinus marmoratus, is also known as the Marbled Blenny is commonly found in the Atlantic Ocean, the Gulf of Mexico and the Caribbean Sea. The Horned Blenny can reach a maximum length of 3.5 inches and should be kept in a tank no less than 30 gallons. It is best to house singly unless kept in a larger tank of at least 70 gallons, and the two are a mated pair. It is a special type of perciform fish that lays eggs in the lumen cavity of a living sponge. Because it displays a distinct red and tanned brown coloration, this marbled blenny can easily camouflage itself according to the surroundings. These Marbled Blennies can be safely kept in a reef-safe aquarium or a large fish tank. They can stay peacefully with other tank mates like Damsels, Clownfish, and Dwarf Angelfish. They become highly territorial when kept with marble blennies of the same species or similar looking fish. The Horned Blenny should be kept in well-established aquariums with large amounts of live rock and natural algae to feed on, and kept on a herbivore diet. The diet can be supplemented with vegetable matter, Spirulina, and herbivore preparations. If there is not enough algae to feed on , the Horned Blenny may nip at small-polyp stony coral and clam mantles. This should be monitored. This Blenny will thrive at a temperature range of 72-78??F and a pH of 8.1-8.4.
