Scartella cristata, commonly referred to as the Molly Miller Blenny, is a popular choice for marine aquarists seeking a peaceful and active algae grazer. This species is well-suited to reef and community aquariums due to its generally non-aggressive temperament and reef-safe nature.
Care Level: Easy to moderate care requirements make Scartella cristata suitable for both beginner and experienced hobbyists. They adapt well to a variety of tank conditions but benefit from stable water parameters.
Temperament and Compatibility: This blenny is peaceful and typically compatible with a wide range of tank mates, including other peaceful fish and invertebrates. It may show territorial behaviour towards conspecifics or similar species, so it is best kept singly or in a well-established community.
Diet: Primarily herbivorous, Scartella cristata grazes on algae and biofilm. Supplement their diet with high-quality marine algae, spirulina-based flakes, pellets, and occasional meaty foods such as mysis or brine shrimp to ensure balanced nutrition.
Minimum Tank Size: A minimum tank size of 75 litres (20 gallons) is recommended to provide adequate swimming space and territories.
Lighting and Water Flow: Moderate lighting is sufficient, replicating natural reef conditions. Moderate water flow is preferred to maintain oxygenation and simulate their natural habitat.
Placement: Provide plenty of live rock with crevices and hiding spots to mimic their natural environment and reduce stress.
Origin: Not Provided.
Maximum Size: Typically grows up to 10 cm (4 inches) in length.
