Distribution

    ASIA: Coastal rivers of Central Vietnam from the An Lao river (Binh Dinh province) to the Phong Nha river (Quang Binh province.)

General Body Form:Male: Long fusiform body with rounded belly and moderately-long, rounded fins. Eight branched dorsal ray fins. Two pair of delicate sensory papillae emerge medially from upper and lower lips. Three to four odontodes at the bottom of the interopercular margin. Female: Same, but slightly more round-bodied.

A small black ocellus divides the caudal peduncle from the origin of the caudal fin. Belly is pearlescent white. Fins are transparent.

Maintenance:Minimum Tank Size and Group Requirements
Shoal of 8 -10: 20 gallons (75.71 liters) or larger.

Tank Set-up
To mimic natural conditions, provide a soft sand or muddy substrate and dense vegetation, including floating plants to dapple the light. Driftwood, branches, dried leaves and stones would complete the environment. Prefers very clean, mature water that is well-oxygenated and has a gentle current.
A very peaceful fish that benefits from company of it’s own kind as well as being part of a non-aggressive, non-competitive community. Spends most of it’s time mid-water, but it will venture out in the open to explore the entire tank. However, one on one, it can be shy and easily intimidated by larger, rowdier tankmates. Small, peaceful fish would make excellent tankmates and might include anabantoids, barbs, small catfish, danios, killifish, rasboras, other small loaches and tetras. A one male to one female stocking ratio is recommended.

Food
OMNIVORE: While likely a micropredator in nature, in aquaria, Y. cruciatus enjoys live or frozen brine shrimp nauplii, daphnia, cyclops, moina, bloodworms, microworm and tubifex as well as sinking pellets, algae tablets and flakes.

 

Biotope:Still, shallow parts of streams and rivers thick with vegetation.

Breeding:

No successful breeding is reported in the aquarium.
