Corythoichthys

Corythoichthys amplexus

Dawson & Randall, 1975

Brownbanded Pipefish

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Indo-West Pacific Ocean: East Africa to Samoa, north to Southern Japan, and south to the Great Barrier Reef.

Size: 4 inches (10 cm)

Natural Environment: Inhabits caves and crevices on fore-reef slopes at depths between 3 - 100 feet (1 - 30 m) where it feeds mainly on zooplankton.

General Husbandry: Rarely seen in the trade, yet quite attractive having a reddish body with white bands.

Those in this genus move by crawling over the substrate, not open water column swimmers. They are best maintained in aquariums, especially reef aquariums, with minimum water currents, as this is also a slow moving species. Aquarium environment should have several caves where it can take shelter as needed, as this is a highly secretive species. Tankmates must be quite peaceful, as pipefish make, good targets for fin-nipping species.

Even though only a live food consumer in the wild, a meaty diet such as enriched live adult brine shrimp and/or enriched frozen brine shrimp, mysis, and krill will usually suffice and should be offered twice daily by dispensing it up stream so the water current will slowly carry it towards the species.

May be difficult to feed in the early days in the aquarium and if so, live enriched adult brine shrimp should be offered several times daily. Over time, it may learn to accept various frozen foods.

Taxonomy:

    Order: Gasterosteiformes

    Suborder: Syngnathoidei

    Family: Syngnathidae

    Subfamily: Syngnathinae

    Genus: Corythoichthys

FYI: Once in an aquarium with many hiding places, may be difficult to feed, let alone be visible.

This is a slow moving fish that can easily get sucked into an open intake siphon; therefore these type intakes must have a strainer on their intake areas.

Those in this genus are often referred to as ‘Dragon Pipefishes.’
