Rummy Nose Rasbora (Sawbwa resplendens)

Rummy Nose Rasboras are great fish for temperament and colour; however, they are recommended for the more experienced aquarist due to these fish needing specific water requirements. But apart from that, they are otherwise hardy and easy enough to look after.

Keeping these fish in the company of their own kind is essential for their welfare, and it would be more beneficial for them if you kept them in groups of 8 or more individuals. Since they are so small, you could keep a school of these fish in an aquarium as small as 40 litres; however, a larger aquarium of around 75 litres is recommended. It will be easier to maintain and will have plenty of room for decor.

You can keep these peaceful Rasboras in a community environment; however, make sure you choose their tank mates wisely as they are timid and slightly nervous due to their small size.

They have a friendly disposition with other fish, and you can house them with tankmates of similar size and behaviours. However, these Rummy Nose Rasboras will develop a distinct pecking order within their own kind, and dominant males can become quite obstinate and combative.

They fare better with a sexually balanced school of around four females to each male and kept in a species only tank. A planted tank with plenty of decors can help keep the peace by breaking up the males' line of sight.

This fish has a slender, streamlined body. The colouration completely differs between the sexes. The male's body is usually a silvery-blue colour, and their nose and the tips of their tails are an orangy-red colour.

The females tend to be a duller silver to light olive-brownish colour with transparent fins with a dark pigmentation spot by their anus. Being scaleless gives both sexes an even colouration.

Feeding

In the home aquarium, the Rummy Nose 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 relatively simple to differentiate male from female Rummy Nose Rasboras. Males are brighter in colour than the females and have distinct red colours on their fins and nose, whereas females are duller and display a dark spot anterior to the anal fin.
