Lipogramma regium
Family: Lipogrammatidae ยท Basslets & Grammas
Also known as: Regal Basslet, Royal Lipogramma
The Royal Basslet is a breathtakingly beautiful deepwater species and one of the crown jewels of the marine aquarium hobby. This tiny fish, reaching a maximum size of only 1.5 inches, features a regal purple body adorned with vibrant yellow horizontal stripes that run along its flanks, creating a pattern reminiscent of royal vestments - hence its fitting common and scientific names. The intensity of its coloration, combined with its extreme rarity, has made it one of the most coveted collector fish in the world.
Lipogramma regium inhabits the deep reef walls of the Caribbean at depths typically ranging from 200 to over 500 feet. At these extreme depths, the species lives among rubble and crevices in near-total darkness, feeding on minute crustaceans and zooplankton. Collection requires specialized deep diving equipment or submersible operations, making each specimen extraordinarily expensive to bring to market. Like other deepwater Lipogramma species, careful decompression during ascent is essential to prevent fatal pressure-related injuries.
As an expert-level species, the Royal Basslet demands meticulous attention to its environmental needs. Subdued lighting is absolutely critical, as the fish originates from an environment with virtually no ambient light. Extensive rockwork with numerous small caves, crevices, and overhangs provides the security this shy species requires. Water quality must be pristine and stable, with no sudden parameter fluctuations. Once properly acclimated in a suitable environment, the Royal Basslet can become a hardy and long-lived aquarium resident, but the initial acclimation period requires exceptional patience and dedication.
Royal Basslets are carnivores that feed on tiny crustaceans and zooplankton in the deep reef environment. In captivity, offer frozen cyclops, baby brine shrimp, finely chopped mysis shrimp, copepods, and high-quality micro pellets. Target feeding near caves and hiding spots is essential during acclimation. Feed small, frequent meals three times daily.
The Royal Basslet is an extremely peaceful, shy species best housed with only the most gentle tankmates. Ideal companions include small gobies, firefish, and other non-aggressive species. Avoid any boisterous, fast-moving, or food-competitive fish. Should not be housed with aggressive species of any size. Completely safe with all corals and invertebrates.
Check CompatibilityCaptive breeding of the Royal Basslet has not been documented. The extreme rarity and cost of specimens, combined with limited knowledge of the reproductive biology of deepwater Lipogramma species, make breeding attempts impractical for most hobbyists. The species is believed to be a pelagic spawner based on observations of related species.
