The Klausewitz Blenny or Lined Blenny is a peaceful, reef-safe marine fish prized for its engaging personality, algae-grazing behavior, and excellent compatibility with reef aquariums. Tank-raised and well adapted to aquarium life, this blenny is an ideal choice for both beginner and experienced reef keepers seeking utility and character in one fish.
The Klausewitz Blenny (Ecsenius sp.) is a small, elongated marine blenny known for its alert behavior, expressive facial features, and constant interaction with its environment. Often seen perching on live rock or darting between crevices, this species brings movement and personality to reef aquariums without disturbing corals or invertebrates.
Unlike more aggressive blenny species, the Klausewitz Blenny maintains a calm and peaceful temperament, making it suitable for community reef tanks, nano reefs, and mixed-species systems. It coexists well with corals, shrimp, snails, and most non-aggressive fish.
With proper hiding spots and stable water parameters, this species establishes territory quickly and becomes a confident, visible inhabitant of the aquarium.
