Tank compatibility

Not compatible with very small shrimp species, should be safe with larger peaceful species. Keep with peaceful fish species only.


May initially be finicky to prepared diets. A common technique for acclimation is clam-on-the-half-shell wrapped in bridal veil. Will eat small meaty foods such as mysis shrimp and other frozen foods when successfully acclimated.

Feeding regime

Feed two to three times a day, keeping the diet varied.
