Toba Betta (Betta Rubra)

Toba Bettas should be kept in a species-only tank in pairs or trios. As long as the aquarium has adequate space and plenty of hiding places, you can keep them with small Rasboras, Tetras, Barbs and Loaches that enjoy similar water conditions. If you house these Bettas with larger, more boisterous species, they will most likely be intimidated and outcompeted for food. While no physical damage is done, there can be some chasing and squabbling over territories.

In an aquarium with dim lighting and a gentle current from an air-powered sponge filter, these Bettas will not only thrive but will also display their best colors. It is also possible to use driftwood roots and branches if you place them so that a few shady spots are created. you can also use PVC piping and clay pots to provide your fish with shelter.

You will need hardy aquatic plants that can survive the same conditions as the fish's water, such as Microsorum, Taxiphyllum, or Cryptocoryne, as well as a few patches of floating vegetation. Keeping this species in acidic conditions with low general hardness would be beneficial.

Adding dried leaf litter enhances the natural feel and offers additional cover, as well as encouraging the growth of microbe colonies as the litter decomposes. The colonies can provide babies with a beneficial secondary source of food. Furthermore, tannins and other chemicals released by rotting leaves give the water a blackwater appearance, much like the natural environment of fish.

Male Toba Bettas typically have dark wine-red colouration on the top half of their body and brilliant red and blue bars on the bottom half. Their fins and tails are bright red, shimmering white or blue on the edges. Like many Bettas, they can quickly change colour depending on their mood. In spawning conditions, the colours can intensify, making the fish glow.

On the other hand, females of this species are less colourful and have a neutral, bland, greyish-brown body colour with a dark bar along their body. There can be a little bit of gold or red, especially along their face, and their fins are often edged with white. Both males and females have additional black barring on their heads and operculum and small dots on their heads in some individuals.

Natural Habitat

Lake Toba


In the home aquarium, the Toba 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.
