Rainbow Shark (Epalzeorhynchos Frenatum) Species Profile & Care Guide
Rainbow sharks are some of the most attractive aquarium fish. However, despite their beauty, the Rainbow Shark has some behavioural issues such as dominance and aggression; this is because they are territorial.
This usually happens as they mature, as juveniles, they are timid and will spend extended periods of their time concealing themselves.
These sharks are active swimmers and tend to spend most of their time dwelling at the bottom of the tank.
The Rainbow Shark is a dark grey fish with vibrant orange-red fins,
They are torpedo-shaped, have a flat stomach with a pointed snout and an upward dorsal fin that may consist of branched rays, along with a forked tail fin like a shark.
Another popular type of the Rainbow Shark is the Albino Rainbow Shark.
Whilst the Albino Rainbow Shark has the orange-red fins, its body is a creamy-white colour.

Natural Habitat of the Rainbow Shark

Other Sharks of interest
Rainbow Sharks are not fussy eaters and will consume most things; as long as it sinks to the bottom of the tank.
Rainbow Sharks will require a varied diet; this will keep their immune system healthy. To achieve this, you should feed them algae wafers or tablets, insect Larvae, frozen or live food and zooplankton. You can also offer them blanched vegetables such as spinach, lettuce and peas.
Breeding the Rainbow Shark
In their natural habitat, Rainbow Sharks tend to mate between October and November around the time they reach sexual maturity.
However, the specific month can be affected by changing seasons, temperature as well as the length of the days.,
When reproducing, the female will lay her eggs, and the male will immediately fertilise them by spraying the eggs with his milt. The eggs will then hatch in around a week.
Unfortunately, in the home aquarium, breeding Rainbow Sharks is extremely difficult, and there has not been any records or proof of success stories.
Large quantities are bred in southeast Asian commercial farms though.
