Ecsenius pictus, known commonly as the white-lined comb-tooth in Indonesia and the pictus blenny in Micronesia,[2] is a species of combtooth blenny family Blenniidae.

[3] The white-lined comb-tooth is found in coral reefs in the central Indo-Pacific area and especially in Indonesia, Philippines and Solomon Islands.

[3] It can reach a maximum length of 5 cm.

[4] Blennies in this species feed primarily off of plants, including benthic algae and weeds,[5] and are commercial aquarium fish.

[3] The specific name "pictus" means "painted" in Latin, and refers to the species' unusual colour pattern.
