Care
Small Corn Blennies are hardy and adaptable, making them suitable for both novice and experienced aquarists. They thrive in aquariums with plenty of live rock and crevices for hiding. These blennies are herbivorous, feeding primarily on algae, so it's important to maintain a healthy growth of macroalgae or provide them with a diet that includes marine algae and vegetable-based foods.
Reproduction
In the wild, Small Corn Blennies are known to lay their eggs in crevices or under ledges. In the aquarium, they may spawn if they are kept in a well-established system with a suitable mate. The male typically guards the eggs until they hatch.
Habitat
Parablennius parvicornis is found in shallow, rocky coastal areas and tide pools. They are adept at blending into their surroundings, which helps them avoid predators. Their natural range extends across the Eastern Atlantic, from the British Isles to Senegal, including the Mediterranean and the Black Sea.
