Likely Reef Tank Suitable
Likely Fish-Only Tank Suitable
Range: Western Atlantic Ocean: West Indies including the Bahamas, and Central America.
Size: 4 inches (10 cm)
Natural Environment: Inhabits nearly vertical cliffs and drop-off on outer reefs areas and found at depths between 30 to 600 feet (10 – 180 m) and feeds on zooplankton.
General Husbandry: Somewhat common in the trade having a purple body with a black patch on the head.
Can be maintained in reef or fish-only aquariums having many rocky hiding places/crevices to investigate or take shelter when needing to do so, as this species is shy, and somewhat secretive. Will defend its hiding place from all on-comers and may annoy small peaceful tankmates!
As to diet, products such as marine fish and crustacean flesh, clams, and other marine meaty foods/freeze-dried foods should be enriched, finely chopped and be fed two to three times daily. Flake foods are also accepted.
Adult enriched live brine shrimp and/or black worms (Lumbriculus variegatus) will also be accepted.
Taxonomy:
Order: Perciformes
Suborder: Percoidei
Family: Grammatidae
Genus: Gramma
FYI: Can be kept in small groups in larger aquaria (over 100 gallons), yet in small aquariums it may be best to maintain only one.
Not possible to distinguish males from females; however, the male is generally larger than the female.
Can jump out of uncovered aquariums.
May pick on/damage small shrimps.
As for the preferred aquarium environment, a vertical wall structure with a large overhanging edge or a cave with only one entrance and large enough to hold all specimens would be ideal.
Captive bred.
Slightly less feisty than G. loreto, Royal Gramma.
Has an odd behavior in the wild of swimming upside-down or in a somewhat head-up or down position as it maneuvers cave areas and/or the overhangs of ledges. This same orientation is seen occasionally in aquariums, bringing concern to some that don’t realize these tendencies are normal. As for tankmates, aggressive damselfishes and wrasses are not good choices.
