Description

The Seaweed Blenny, also known as the Rock Blenny, is a fascinating, comical, and unique saltwater fish. It has a long, slender body with various spots and patterns that help it blend into its surroundings. It has a distinctive elongated snout which it uses to feed on small invertebrates and algae. It is well-known for its incredible jumping abilities and its habit of perching on rocks and coral.

Reef Safe

Yes, they are considered reef safe but may nip at small-polyped stony coral and clam mantles.

Environment

Seaweed Blennies need a tank with plenty of live rock for hiding and grazing. They prefer a tank with a tight-fitting lid to prevent them from jumping out. They can tolerate a range of water conditions, but stable parameters are crucial for their health.

Behavior

Seaweed Blennies are generally peaceful and tend to keep to themselves. They are not overly active swimmers and prefer to hop from rock to rock. They are territorial and will defend their chosen home against intruders.
