TAXONOMY
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii (ray-finned fishes)
Order: Perciformes (Perch-likes)
Family: Grammatidae (Basslets)

Genus/species: Gramma loreto

GENERAL CHARACTERISTICS: Bicolored: purple (appearing blue underwater) in front, bight orange-yellow behind. Length to 8 cm (3.1 in)

DISTRIBUTION/HABITAT: Western Central Atlantic (Caribbean, Bahamas, Bermuda). Found in caves or under ledges. Swim with belly toward substratum, thus under ledges seen upside down. 

DIET IN THE WILD: Feed on ectoparasites of other fishes.

REPRODUCTION/DEVELOPMENT: External fertilization. Prior to spawning, some males establish nest sites, using small holes and crevices in the substratum. Females travel to male nests for egg deposition around dawn.  Males guard and maintain the nest.   

CONSERVATION: IUCN Not Evaluated

REMARKS: Often rests or retreats when alarmed to a stereotypic “upside down” posture near cave roofs.
