Choosing the right blenny for your tank
Most blennies are comfortable in tanks of 20 to 30 gallons and up, though algae-grazing species such as the lawnmower and sailfin blennies do best in mature aquariums of 30 gallons or more where natural algae growth is available. Provide plenty of live rock with small holes and crevices, and keep a lid on the tank since blennies can jump. Water parameters follow the usual reef standards: 72-78°F, specific gravity around 1.023-1.025 and pH 8.1-8.4.
Blennies are peaceful toward most fish but territorial toward other blennies and similar bottom dwellers, so keep one per tank unless the system is large. Herbivorous species need algae-based foods such as spirulina flakes, nori and algae wafers, while plankton feeders like the Midas blenny take mysis, brine shrimp and small pellets. Blennies are generally reef safe, although a few species may occasionally nip at clam mantles or fleshy corals.
