Freshwater Pipefish

Geographic Origin and Biotope: India (Assam, Bengal) and Bangladesh. Inhabits clean, fast-flowing rivers, hiding among submerged roots and dense riparian vegetation.

Taxonomy and Morphology: Deocata Pipefish (Microphis deocata). Freshwater pipefish. Closely related to seahorses (Syngnathidae family). Armored, tubular and extremely elongated body, pipette-like mouth.

Social Behavior: Peaceful, slow and methodical. Spends the days peering at every single leaf with its independent eyes (similar to those of chameleons) in search of micro-prey.

Coloration and Sexual Dimorphism: Females are the showy sex (a rare thing): they present a spectacular rainbow-colored ventral "sail" (red, green, blue, yellow) that they unfold during courtship. Males are gray/brown and equipped with a ventral brood pouch.

Aquarium Setup: Long tank (at least 80-100 cm / 32-40 inches) with little current, densely planted (Vallisneria gigantea, Ceratophyllum) to offer vertical holds. Soft sand bottom.

Diet and Feeding: Lethargic micro-predator. Accepts EXCLUSIVELY live food. Needs a constant supply of brine shrimp nauplii, daphnia, moina or tiny mosquito larvae. Will categorically ignore dry food.

Water Quality: Hard and moderately alkaline water (PH 7.2-8.0). Suffers in excessively soft and acidic waters. Requires highly oxygenated water but with low mechanical flow (sponge filtration or spray-bar directed to the glass).

Compatibility and Tankmates: Best kept in a dedicated tank (Species tank). Any other fish would steal the food before the very slow pipefish can fixate on the prey. Only static companions (Otocinclus) or small snails are tolerated.

Aquarium Reproduction: Very complex. The female exhibits the iridescent sail; after the dances, she transfers the egg filaments into the male's ventral pouch. The male incubates the eggs and "gives birth" to tiny fry that need live infusoria.

Risks and Diseases: Guaranteed starvation in inadequate tanks. If placed in community tanks, they will waste away in a few weeks. Not having a real stomach (like seahorses), they must eat continuously all day long.
