Behavior & Husbandry

Molly Miller Blennies spend most of their time perched on rockwork while grazing algae and exploring the aquarium. They are extremely hardy, adaptable, and well suited for both beginner and advanced reef keepers.

Biota captive-bred specimens are already well acclimated to aquarium life and typically transition very easily into established reef systems.

In addition to algae grazing, Molly Miller Blennies are also known for occasionally helping control nuisance pests such as aiptasia in some aquariums.
