Bicolor Basslet

The Bicolor Basslet is one of the rarest and most sought-after deepwater fish in the marine aquarium hobby. This diminutive gem features a stunning bicolored pattern with a vivid pink to magenta anterior half that transitions abruptly to a bright yellow posterior half, creating an eye-catching contrast that makes it instantly recognizable. At a maximum size of only 1.5 inches, it is among the smallest basslets available, yet its extraordinary beauty and extreme rarity command premium prices that place it among the most expensive marine fish in the trade.

In the wild, Lipogramma klayi inhabits deep reef walls and rubble zones in the Caribbean at depths typically ranging from 150 to over 600 feet. This extreme depth requirement makes collection extraordinarily difficult and expensive, requiring advanced mixed-gas diving techniques or submersible operations. The species lives a secretive life among deep reef crevices and rubble, darting between hiding spots to capture tiny crustaceans and zooplankton. Specimens must be carefully decompressed during collection to prevent fatal barotrauma.

Due to its deepwater origin and extreme rarity, the Bicolor Basslet is classified as an expert-level species. Successful husbandry requires subdued lighting conditions that replicate the near-darkness of its deep reef habitat, extensive rockwork with numerous small caves and crevices, and a calm, peaceful tank environment free from aggressive or food-competitive species. Once properly acclimated, this species can prove surprisingly hardy, but the initial adjustment period is critical and requires patient, attentive care including target feeding near hiding spots.
