Common name: Mushroom coral shrimp

General information

The Coral Shrimp, Hamopontonia corallicola, is a small, cryptic species of shrimp that is often overlooked due to its small size and excellent camouflage abilities. It is a member of the Palaemonidae family and is known for its close association with certain soft corals, particularly those of the genus Sarcophyton. This shrimp is not as well-known or as commonly kept as some other ornamental shrimp in the reefkeeping hobby, but it can be a fascinating addition to a mature reef aquarium with established soft coral populations.

Care

Hamopontonia corallicola requires a well-established aquarium with plenty of live rock and soft coral hosts. They are sensitive to water quality and require stable conditions with excellent water clarity. Due to their small size and specific habitat needs, they are best suited for nano or smaller reef tanks where their unique behaviors can be observed without them being outcompeted by larger tank mates. Feeding can be challenging as they scavenge on microorganisms and detritus, so a mature tank with a natural source of food is essential.

Reproduction

Little is known about the reproductive habits of Hamopontonia corallicola in the wild or in captivity. However, like many marine shrimps, they are likely to have a planktonic larval stage, which can make captive breeding a challenge for hobbyists.

Symbiosis

Hamopontonia corallicola exhibits a fascinating symbiotic relationship with soft corals, particularly those in the genus Sarcophyton. The shrimp benefits from the protection provided by the coral's toxic defenses against predators, while the coral benefits from the shrimp's cleaning services, as it removes detritus and potentially harmful parasites.

Habitat

This species is found in the Indo-Pacific region, often associated with soft corals in shallow reef environments. They are adept at blending into their surroundings, making them a challenge to spot in the wild.
