Royal Gramma

Gramma loreto

Royal Gramma is a small Caribbean reef basslet prized for its vivid purple front half and yellow rear half. It lives close to rocky caves and coral ledges, where it picks small zooplankton from the water column and defends a tight shelter.

Môi trường sống

Shallow coral reefs, rocky ledges, and crevices; usually under overhangs or inside caves from the surf zone to moderate reef depths in the western Atlantic/Caribbean.

Ghi chú mồi

Not a practical angling target; mostly taken in aquaria and not targeted by sport fishers. In captivity it accepts tiny meaty foods such as mysis, brine shrimp, copepods, and finely chopped seafood.

Hành vi

A secretive reef dweller that hovers upside down or head-down near shelter, darting out to grab tiny drifting prey. It is territorial around its cave and often retreats quickly when disturbed.

Thận trọng

Reef-associated species; no major human consumption role. Avoid collecting from protected reef habitats and check local marine aquarium collection rules.

Ghi chú câu cá

If encountered while reef fishing, use very light tackle and tiny hooks with small pieces of shrimp or baitfish, but release promptly. It is far more of an ornamental reef species than a gamefish.
