Care

Tompot Blennies are hardy and adaptable, making them suitable for both beginner and advanced hobbyists. They require an aquarium with plenty of live rock for hiding and grazing, as they enjoy picking at microalgae and small invertebrates. A varied diet that includes marine algae, frozen and dried foods will help maintain their health and vibrant coloration.

Reproduction

In the aquarium, breeding Tompot Blennies can be a challenge. They are not commonly bred in captivity, and little is known about their reproductive habits in home aquariums. However, in their natural habitat, males are known to guard and care for the eggs until they hatch.

Habitat

Tompot Blennies are native to the Eastern Atlantic, from the British Isles to the coast of Morocco, including the Mediterranean and the Black Sea. They are typically found in shallow waters, often not deeper than 20 meters, where they inhabit rocky reefs and kelp forests.
