Likely Reef Tank Suitable
Likely Fish-Only Tank Suitable
Range: Indo-Pacific Ocean: East Africa to Central Pacific Ocean.
Natural Environment: Inhabits nutrient rich tidepools and shallow lagoons.
General Husbandry: Common in the trade. Generally has blue surface with a somewhat whitish mouth area.
Tentacles are wart-like or completely absent and there are no surface ribs.
The only species in this genus to stay flat against the substrate.
Requires slow water movement and dim to moderate lighting, preferably indirect lighting.
May accept feedings of microplankton foods, and/or newly hatched brine shrimp.
FYI: Easily propagated from cuttings.
Metallic blues specimens prefer stronger lighting, e.g., >PAR 150
Possibly now placed in the Actinodiscus genus.
