Sidestripe Rasbora (Rasbora paviana)

The Sidestripe Rasbora is a peaceful and hardy species of fish, making it ideal for the larger, well-furnished community aquarium. In addition, Rasboras require no unique water chemistry so you can pair them with a wide variety of popular fish.

Other Cyprinids and Livebearers, Tetras, Rainbowfish, Gouramis, Loaches and Catfish could make good tank mates for Sidestripe Rasboras.

Another worthwhile project would be to design a community aquarium based on one of their river basins or native countries.

To get the most out of Sidestripe Rasboras in an aquarium, keep them in a group of at least six, preferably more. They will display better colours in the presence of their species, will be less nervous, and the display will appear more natural.

You can also construct a river tank manifold to provide natural unidirectional flow by adding gravel, rocks, or smooth boulders to the substrate. In addition, you can add aquatic plants and driftwood branches to the tank for aesthetic value.

In these conditions, most plants will not thrive, but hardy species such as Bolbitis, Anubias or Java Fern will do well.

Because these Rasboras are capable jumpers and can escape through the tiniest gaps, the aquarium lid must be very tightly fitted.

Sidestripe Rasboras have a diamond-shaped blotch on their caudal peduncles instead of a narrow black longitudinal stripe. They have dark reticulated patterns around their scale margins; some have black tips on their caudal lobes. Furthermore, these Rasboras have yellowish dorsal fins with or without black tips.

In the home aquarium, the Sidestripe Rasbora will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements.

Providing additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide additional benefits to your fish's health and well-being but is not a must for this fish.

It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages.

This fish is an omnivore in the wild, meaning it will consume some vegetable matter. Although most modern fish foods take this into account and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.

Sexual Dimorphism

Male and female Sidestripe Rasbora are difficult to distinguish, but sexually mature females usually have rounder bellies and are slightly larger than males.
