Rummy Nose Tetra (Hemigrammus rhodostomus)

The Rummy-nose tetra is a torpedo-shaped fish, and its body colour is a translucent silvery colour with a greenish tint. Iridescent green scales are frequently seen on the fish at the point where the fontanel meets the body, and they have a vibrant red colour nose which is quite striking. The tail has a zebra-like design of black and white horizontal stripes.

Rummy nose tetras are a shoaling fish that does well in groups of 6 or more, creating a lovely visual display in the aquarium.

This species has a peaceful nature and can tolerate slightly higher temperatures, but they may be pretty sensitive to a change in water parameters, so you need to be careful.

They can happily be housed with other community fish as long as they are not aggressive or predatory fish.

They need hiding places and plants to hide away in incase they feel stressed.

In the home aquarium, the Rummy Nose Tetra 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

Sexing Rummy nose tetra individuals is quite tricky as there is no obvious way to distinguish them by your eyes. Some people say that females have a slightly larger body than males.
