Quote from: The Mini Reef Aquarium Jeffrey Kurtz... The Royal Gramma was specifically designed to serve as the pefect mini reef inhabitant. G loreto will co exist peacefully with most other reef friendly species, showing aggression only towards conspecifics and interlopers attempting to enter its cave, which it will defend with vigor.
Quote From: The Nano Reef Handbook Chris R Brightwell ... one species,the Royal Gramma(Gramma Loreto) is hardy even tempered and affordable. Members of this family are relatively mild mannered(particularly when compared to the Dotty Backs) leaving most tankmates too large to swallow alone.
Quote From: Marine Fishes Scott W Michael....a hardy intenselycolourful aquarium fish that tends to do well even for beginner aquarists. It is generally non aggressive, but will viciously defend its preferred hiding place from intrusion. An irregular vertical reef wall or an overhang of live rock will replicate its natural habitat........will build nests and spawn in captivity.
