Nego Dagua Tetra (Hyphessobrycon negodagua)

Known for its beauty in well-planted aquariums, the Nego Dagua Tetra is a small, rare, new species in the hobby. Furthermore, these Tetras are relatively easy to maintain and have a peaceful disposition.

It is important to keep the Nego Dagua Tetra in groups of at least eight individuals, preferably more, because it is a shoaling species in nature. Other small peaceful fish such as Micro Rasboras, other small Tetras, and Dwarf Barbs would be ideal tankmates for these Tetras. However, because of their small size, it may be best to avoid larger, boisterous fish.

The ideal aquarium setup for Nego Dagua Tetras could include sand or fine gravel substrate with plenty of vegetation consisting of either live or synthetic aquatic plants and areas of rocky structures, as well as some driftwood roots and branches. The water should be on the warmer side, slightly acidic, and the pH needs to be stable. They can tolerate other water conditions if they are acclimated slowly and are not subjected to rapid fluctuations in either water temperature or chemistry. Lastly, these Tetras will appreciate an aquarium environment with gentle water flow providing water movement throughout the aquarium while not creating too strong a current.

The Nego Dagua Tetra has a dark greyish body with black colouration on the posterior part of their body. These fish also possess bright white thickish markings on their dorsal and anal fin that contrasts nicely with the dark colouring of this fish. In addition, their pectoral and caudal fin is the same colour as their bodies, and they lack an adipose fin.

Feeding

In the home aquarium, the Nego Dagua 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

It is relatively straightforward to differentiate between the male and female Nego Dagua Tetra. The male's body colouring is much darker than the females, and their dorsal and anal fin is a little longer and slightly more pointed than the females. In contrast, females are much duller than males and display a silvery midlateral stripe and a darkish blotch on their caudal peduncle.
