The Blennius Tétacularis fish is a little fish from the Blenniidae family. It measures about 10 cm long and has an elongated body and flattened laterally. Its color generally varies between gray and brown, with darker spots on the body and vertical stripes on the fins. The Blennius Tenacularis has two dorsal fins, a caudal fin, an anal fin and a pectoral fin. His head is wide and has round eyes and his mouth is small and sharp.

The Blennius Tentacularis lives mainly in the rocky and sandy coastal waters of the Northeast Atlantic, the English Channel and the North Sea. It feeds mainly on small crustaceans and molluscs which he finds by searching the bottom of the rocks and crevices. The Blennius Tétacularis is a lonely and territorial fish, which moves slowly by crawling on the bottom of the rocks and reefs.

The Blennius Tentacularis reproduces in summer. The female lays her eggs on the rocks and makes them fertilize by the male. The eggs hatch about a week later and the larvae are released in the water. The larvae feed on plankton until they reach adulthood, generally after a few months.

The Blennius Tétacularis is considered an unthanded species and it is widely spread in its natural habitat. However, it can be affected by water pollution and the destruction of coastal habitats.

Unknown in aquarium, but must be possible in a large large tank (300 to 400 L), placing several individuals.
