Ophiarachna incrassata is a popular brittle star species prized for its distinctive, thick arms and active scavenging habits. This invertebrate is an excellent addition to marine aquariums, particularly reef setups, where it contributes to tank hygiene by consuming detritus and uneaten food.
Care Level: Easy to moderate care requirements make this brittle star suitable for hobbyists with some marine aquarium experience.
Feeding: Primarily detritivorous, Ophiarachna incrassata will scavenge leftover food and organic debris. Supplementary feeding with finely chopped meaty foods such as mysis shrimp or marine pellets is recommended to ensure optimal health.
Compatibility and Reef Safety: This species is generally reef safe and compatible with most peaceful tank inhabitants. However, it may prey on very small or slow-moving invertebrates, so caution is advised when housing with delicate species.
Tank Requirements: A minimum tank size of 75 litres is recommended to provide adequate space and stable water conditions. Moderate water flow is ideal, mimicking natural reef environments, and lighting requirements are not critical as this species is nocturnal and avoids bright light.
Placement: Provide plenty of live rock or crevices for shelter and hiding spots. This brittle star is nocturnal and will often remain hidden during daylight hours.
Origin and Size: Origin is not provided. This species can reach a maximum arm span of approximately 20 cm, depending on individual size.
