Yoma Danio (Danio feegradei)

Yoma Danios are peaceful fish; however, you should ideally house them in a large aquarium containing similarly sized robust species due to their constant activity and their lively feeding behaviour.

Although not aggressive, these Danios may disturb very slow-moving or timid tankmates, so avoid keeping them with this sort of fish. Ideal tankmates for these Danios include Loaches, Cichlids, Gouramis, Catfish, larger Tetras and many Cyprinids. It would be best if you did not house them with much larger or more aggressive fish species that may see them as prey.

Though sociable by nature, Yoma Danios are a shoaling fish rather than a schooling fish and they only group together tightly when they feel threatened. At other times rival males often battle. However, if you maintain these fish in groups of 8 or more, this will allow the weaker fish of both sexes a break from the alpha individuals, which can be pretty aggressive at times.

Yoma Danios look especially effective in a heavily-planted aquarium with a dark substrate and may seem duller in minimalistic setups. The ideal aquarium setup would mimic a flowing stream or river with a substrate of differently sized gravel and rocks alongside smooth stones or boulders.

You can use extra powerheads or filter outlets to improve the flow; however, you should avoid very fast-flowing currents because small Danios usually inhabit calmer waters in the wild. It would benefit your fish if you also added some driftwood roots and branches and some hardy aquatic plants such as Anubias or Microsorum that can grow on the decor.

Your aquarium will need to have a tight-fitting lid because these Danios are excellent jumpers and can fit through the smallest of gaps.

Yoma Danios have blueish-silver colouration along their sides, and they have two rows of gold spots along their flanks. You can find the first row of dots (usually around 14) along the lateral line, and the second row of dots (generally around 6) are just below the lateral line.

The males possess an orange border on their anal, pectoral and ventral fins, and the females include a white border. In addition, both the males and females have an orange spot just behind their gill cover and a big, dark spot at the base of their caudal fin.

Feeding

In the home aquarium, the Yoma Danio 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 easy to differentiate between the male and female Yoma Danios. Males are more colourful, smaller and somewhat slimmer, and they have orange colouration on the edges of their ventral and anal fins, whereas the females are white. If you have multiple males, one or more individuals will generally develop an alpha position and become even more intensely coloured.
