How to feed the Roseline shark?
Feeding the Sahyadria will not be a problem. Indeed, it easily accepts many varieties of food. You can therefore offer him freeze-dried food classically used in aquariums, if possible of high quality! Alternate with frozen or live prey (artemia, chironomid larvae, mud worms, daphnia...).
What kind of behavior does the Roseline shark have?
The Roseline shark has a quiet and peaceful temperament. Nevertheless, he's a good swimmer and he's generally quite lively. However, you will notice increased activity at dawn and in the evening (he is calmer during the day).
Within the group, a few clashes can sometimes occur. Indeed, these social fish establish a stable hierarchy. Generally, once the leader is established, everyone lives peacefully.
These fish can change colour. When they tarnish (they look whiter) it is due to stress. It can be either poor water quality, an unsuitable social group, not enough vegetation or a newcomer to the aquarium. Conversely, it seems that they intensify their colours (or even change them) during the breeding season.
Who can live with the Roseline shark?
Pacific and non-territorial, you will be able to keep this species in a well-studied community aquarium.
The Roseline shark is a gregarious fish that absolutely needs to be kept in groups. Count a minimum of 8 to 10 individuals for its well-being.
As for other species, although there are no restrictions on the character of the Sahyadria, it is still preferable to choose fish that are fast (because of the current in the aquarium) and that will not be disturbed by the sometimes intense activity of the Roseline shark. For example, you can choose between Barbus or Danios.
How to breed the Roseline shark?
Reproduction is difficult. Indeed, to trigger spawning, it seems that a large group is necessary (at least fifteen specimens). The progressive drop in pH also seems to be a trigger. Most of the fish sold are obtained with hormone-boosted reproduction. Finally, it should be noted that a few risky reproductions have been reported by private individuals, as well as others more controlled by public aquariums.
Which aquarium for the Roseline shark?
In its natural habitat, the waters are very rich in oxygen. The current is fast and the vegetation is dense.
To recreate these conditions in captivity, install good filtration to ensure a constant flow, good water quality and good mixing. For this, an external filter is very suitable. Also, change the water regularly to keep the water as clean as possible. For the parameters, it will help in neutral water with a pH 7 and a hardness of 10°dGH.
Plant your aquarium abundantly but leaving enough space for the fish to expend their energy. Ideally, start with Asian plants.
For the soil, choose sand or fine gravel and sprinkle with smooth stones. Finally, decorate with roots and driftwood.
Because of its high tolerance to water temperature, you don't need to install an immersion heater in your Roseline shark tank. However, note that it may still be necessary for your vegetation!
Be careful because the Roseline shark is a good jumper! If you don't want to find your grilled fish or fish on the ground, remember to protect your lighting system and cover your tank.

Beware of confusion with the much more aggressive species Sahyadria chalakkudiensis. This fish is also less colourful and larger.
In India, its name means "bleeding eyes".
There is a "Grey and gold Denison barb" variant of this species.
Very popular in Asia, this fish is unfortunately on the red list of endangered species. Although fishing for the aquarium market is largely responsible, it is now regulated. The degradation of its natural environment also contributes to its progressive disappearance.
