Origin[edit | edit source]

Asia: Mekong, Chao Phraya and Xe Bangfai basins and Maeklong basin.

Sexing[edit | edit source]

Males are slimmer than the females and have black lines on the anal fin.

Tank compatibility[edit | edit source]

Keep a single Ruby Shark to a tank, will be aggressive and territorial towards other shark-like fish. Will be fine with more robust mid and top swimming fish. They are best kept with similar-sized fish and not smaller fish.

Diet[edit | edit source]

An omnivore that will eat a variety of foods. Flakes, freeze dried, frozen, raw/live, and pellets are all acceptable forms of food. Some favourites include shrimps, worms, and veggies.

Feeding regime[edit | edit source]

Feed once or twice a day.

Environment specifics[edit | edit source]

Provide plenty of hiding places (caves, rocks and plants) allowing for this species territorial behaviour. Prefers a sandy substrate. This sometimes fast moving fish appreciates open swimming space as part of it's environment.

Behaviour[edit | edit source]

This fish can become aggressive with other, smaller fish in your tank that invade its territory. They will fight with the Red Tail Shark. They have been observed in home aquaria to harass other fish of similar colour and/or shape to themselves.

Identification[edit | edit source]

This fish has an elongate shark-like shaped body, giving it its common name, the base colour of the body is usually dark grey with all fins coloured red. There is also an albino morph available which has a colour-less body but still exhibits the red fins.
A similar species, Epalzeorhynchos munense, may be sold under the same common name, the difference being on the pelvic and pectoral fins, on the E. munense they have black margins.
