Marine Fish • Reef-Safe • Algae Grazer • Rock-Crevice Percher
📋 The Linear Blenny (Ecsenius lineatus) features a bold dark stripe running from eye to tail over a lighter body, a pair of slender cirri above its eyes, and a body form suited for rock-crevice perching. It is highly active, often seen hovering over live rock, grazing algae films and darting into crevices when alarmed.
Because of its compact size and peaceful behaviour, it’s a strong candidate for reef systems; however hobbyists should monitor it in tanks dominated by delicate SPS corals, as individual behaviour may vary.

⚪ Efficient Algae Grazer: Supports tank cleanliness and ecology
