Common name: zoanimir's blenny

General information

The Adriatic Blenny, scientifically known as Parablennius zvonimiri, is a small, characterful fish that is not commonly found in the aquarium trade but can be a unique addition to a temperate marine aquarium. It is named after Zvonimir, a Croatian king, reflecting its presence in the Adriatic Sea. These blennies are known for their curious behavior and distinctive appearance, with a mottled pattern that helps them blend into their rocky surroundings.

Care

Adriatic Blennies are relatively hardy and can adapt to life in captivity if provided with an environment that mimics their natural habitat. They require an aquarium with plenty of live rock for hiding and grazing on microalgae. These fish are not aggressive towards other tank mates but can be territorial with their own kind. A varied diet of marine algae, small crustaceans, and quality prepared foods will help maintain their health.

Reproduction

In the wild, Adriatic Blennies are known to lay eggs in crevices within the rocks. The male guards the nest until the eggs hatch. While breeding them in captivity is not common, providing a stable environment with plenty of hiding spaces can encourage their natural breeding behavior.

Habitat

Parablennius zvonimiri is native to the rocky coasts and shallow waters of the Adriatic Sea. They are typically found in areas with abundant algae growth, which provides both food and shelter. Their natural range includes the coastal waters of countries bordering the Adriatic Sea, such as Croatia, Italy, and Slovenia.
