Solenostomus paegnius
Family: Solenostomidae ยท Pipefish
Also known as: Rough-snout Ghost Pipefish, Rough Snout Ghostpipefish
The Roughsnout Ghost Pipefish is one of the rarest and least documented members of the ghost pipefish family, distinguished by a textured, somewhat rough-surfaced snout that gives the species its common name. Its body is slender and moderately sized at around 5 inches, with coloration varying from pale pink and white to mottled brown, adapting to match its immediate surroundings. Like all ghost pipefish, it possesses enlarged, fin-like pelvic fins that the female uses to brood eggs, creating the appearance of a delicate, leaf-like organism drifting in the current.
In the wild, Solenostomus paegnius has been documented primarily in the Western Pacific, particularly around Indonesia and the Philippines. It is typically found on reef slopes and in sheltered bays at moderate depths, often associated with soft corals, whip corals, or debris where it can camouflage effectively. Sightings are uncommon even for experienced underwater photographers, reflecting either genuine rarity or exceptionally effective camouflage, likely a combination of both. Pairs are occasionally encountered drifting together near the substrate.
Keeping the Roughsnout Ghost Pipefish is a supreme challenge that should only be attempted by the most experienced and dedicated marine aquarists. Virtually nothing is published about its successful captive maintenance, and the general principles that apply to all ghost pipefish apply here with even greater emphasis: an absolute requirement for live foods, inability to compete with any other fish, extremely short expected captive lifespan, and the need for a mature system with a highly productive refugium. Specimens are rarely collected and even more rarely offered for sale, making this a true collector's species.
Roughsnout Ghost Pipefish are ambush micro-predators that feed exclusively on tiny live crustaceans such as copepods and mysid shrimp. They require a constant supply of live foods, as they will not accept frozen or prepared diets. A highly productive refugium is absolutely critical. Enriched live baby brine shrimp may serve as a supplemental food source. Continuous feeding opportunities throughout the day are necessary due to the species' slow, one-at-a-time feeding method.
The Roughsnout Ghost Pipefish must be kept only with the most peaceful, non-competitive species. A dedicated species-only setup is the only realistic option. Seahorses are the only suitable companions, and even other pipefish species may compete for limited food resources. Any source of stress or food competition must be eliminated entirely. Completely reef-safe and poses no threat to corals or invertebrates.
Check CompatibilityLike all ghost pipefish, the female carries the eggs in a brood pouch formed by modified pelvic fins. Virtually nothing is documented about captive breeding of this species. General ghost pipefish breeding protocols would apply: paired specimens, adequate nutrition for the brooding female, and the ability to raise extremely tiny juveniles on microscopic live foods. No successful captive breeding has been documented.
