Red Skirt Betta (Betta Falx)

Red Skirt Bettas are not generally seen in the aquarium hobby, but they have a reputation of being an excellent aquarium inhabitant when given suitable conditions. Unlike the common Betta species, both the male and female are generally peaceful to their own kind, even if you house males with other males. When kept in groups, this fish will often show captivating courtship behaviour, especially between males competing for female attention.

It would be best if you kept Red Skirt Bettas in a species-only aquarium or a community aquarium with peaceful species that inhabit similar environments in the wild; timid Loaches and small Cyprinids would be ideal. It would be better if you avoided housing these fish with larger, more lively and aggressive species; otherwise, they will feel intimidated and will be outcompeted for food.

You can maintain these Bettas in a fully-decorated aquarium, although most breeders prefer not to use a substrate to make the aquarium easier to maintain.

In an aquarium with plenty of driftwood roots and branches, Red Skirt Bettas will thrive. By adding dried leaf litter, you will further enhance the natural feel and provide additional cover for the fish. Aside from providing food for the babies, decaying leaves release chemicals and tannins that are beneficial to them.

Red Skirt Bettas prefer dim lighting, so adding hardy plants and floating plants will help diffuse the light. These fish do not like swift currents; therefore, a small air-powered sponge filter will be ideal. These Bettas are fantastic jumpers, so make sure your aquarium has a tight-fitting lid. Lastly, ensure you do not fill your aquarium with too much water as they require infrequent entry to the layer of humid air that forms above the water surface.

The body and dorsal fin of the Red Skirt Betta males are primarily reddish-brown with greenish-blue scales. In addition, they have a dark blue-black edge to their anal and caudal fin. The females have a brownish body with dark horizontal stripes and a tail spot.

In the home aquarium, the Red Skirt Betta 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 between the male and female Red Skirt Betta. Males have broader heads, have a much darker stripe on their anal fin and are larger, have longer fins and are much more intensely coloured than the females. In contrast, females are smaller, have more pointed heads, are duller and lack intricate fins.
