Simons Rasbora (Rasbora simonbirchi)

Simon Rasboras are a very peaceful and adaptable species making them an ideal member of a larger, well-furnished community aquarium. In addition, these Rasboras have no particular demands regarding water chemistry; therefore, you can combine them with multiple of the most popular fish in the hobby.

In addition to other Cyprinids, Rasbora simonbirchi would make a good tank mate for Livebearers, Tetras, Gouramis, Rainbowfish, Catfish, and Loaches. Building a community aquarium based on their native countries or river basins would also be worthwhile.

The Simon Rasbora is naturally sociable; therefore, it would be best to keep them in a group of at least six individuals, although keeping more will get the best out of them in the aquarium. Then, like most fish, they will display better colours in the presence of their kind, will be less anxious, and the display, on the whole, will be more natural-looking.

You can construct a river tank manifold to allow natural unidirectional flow, gravel, different-sized rocks, or smooth boulders as a substrate.

For aesthetic value, you can further furnish the tank with aquatic plants and driftwood branches. Hardy species like Java fern, Bolbitis, and Anubias will thrive in these conditions.

Rasboras are surface-dwelling, accomplished jumpers who can escape through even the tiniest gap in the aquarium's lid.

From the posterior margin of the eye to the caudal fin, the Simon Rasbora has an iridescent green stripe running along the middle of its body.

Additionally, these Rasboras exhibit crescent-shaped black marks along the posterior margins of the midlateral scales, as well as a small black spot above the anal fin. Finally, the fins are transparent with a reddish-orange hue.

Feeding

In the home aquarium, the Simons 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

It is somewhat challenging to differentiate between the male and female Simon Rasbora; however, Sexually mature females are rounder in their bellies, are often a little larger than males, and usually have lighter colouration.
