Halichoeres bivittatus
Family: Labridae ยท Wrasses
Also known as: Slippery Dick Wrasse, Two-Striped Wrasse
The Slippery Dick is one of the most common wrasses found throughout the Caribbean and Western Atlantic, and its name derives from its slippery, mucus-coated body that makes it difficult to hold. This medium-sized Halichoeres species displays attractive horizontal striping along its body with a combination of green, yellow, and pink tones that intensify in dominant males.
In the wild, Slippery Dicks are found in virtually every Caribbean reef habitat, from shallow seagrass beds to deeper coral reefs. They are opportunistic feeders that forage constantly over the substrate, picking off small invertebrates, worms, and crustaceans. This tireless foraging behavior makes them effective pest controllers in the home aquarium, where they will hunt flatworms, bristleworms, and other nuisance organisms.
The Slippery Dick is among the hardiest wrasses available, tolerating a wide range of conditions and readily accepting prepared foods from the first day in captivity. Its peaceful temperament, manageable size, and robust constitution make it an excellent choice for beginner marine aquarists. Like other Halichoeres wrasses, it requires a sand substrate for sleeping and a secure lid to prevent jumping.
Slippery Dicks are opportunistic carnivores that feed on small invertebrates, worms, crustaceans, and occasionally small fish in the wild. In captivity, they eagerly accept frozen mysis shrimp, brine shrimp, chopped seafood, marine pellets, and flake food. They are not picky eaters and typically feed aggressively from the first day. They actively hunt aquarium pests including flatworms and bristleworms. Feed two to three times daily.
The Slippery Dick is peaceful and compatible with virtually all community reef fish. It coexists well with clownfish, tangs, angelfish, blennies, gobies, and other wrasses. It will consume small pest invertebrates but does not harm corals, clams, or ornamental shrimp. An excellent community fish that rarely causes problems. May spar mildly with other Halichoeres wrasses.
Check CompatibilitySlippery Dicks are protogynous hermaphrodites. Terminal phase males are more brightly colored and maintain territories. Spawning occurs in the water column with pelagic eggs, typically during late afternoon. Captive breeding has not been achieved. Specimens are collected from Caribbean and Western Atlantic waters.
