Red Devil Tetra (Hyphessobrycon piranga)

Red Devil Tetras are a relatively rare species in the aquarium hobby. They are stunning, peaceful, sociable and active little fish that only came about in 2018.

Red Devil Tetras are schooling fish in nature, so, therefore, they should be kept in a group of at least eight individuals, preferably more. Keeping these Tetras in larger groups will not only give your aquarium an array of colours, but it will also give your aquarium a more natural-looking display as well as making your fish feel more comfortable so they can show off their true behaviours.

Ideal tankmates for Red Devil Tetras could include peaceful species such as other Tetras, smaller Barbs, Rasboras, smaller Danios and Corydoras Catfish. Shrimps can also make suitable tankmates, although shrimplets may get eaten.

Red Devil Tetras are a pretty easy species to keep as they have no particular demands when it comes to their water conditions. However, these Tetras will appreciate a slight current to mimic their natural biotope.

The ideal aquarium setup for these fish will include a substrate of either sand, gravel or pebbles and plenty of plants as they live in areas with an abundance of plants. Adding leaves to the bottom of your aquarium will also be beneficial for these Tetras.

Red Devil Tetras have a creamy-yellowish body contrasted with a wide, dark brown vertical stripe that runs across their flank from their nose, through their eye towards their tail root. Above this, they possess a silvery-white bar. The males have red fins as well as a faint red hue on their bodies, whereas the female's fins and bodies are more yellow.

Natural Habitat

Red Devil Tetras are endemic to the Rio Verde and Rio Juruena drainages of Brazil's upper Rio Tapajós basin in South America. They inhabit clear water rivers and streams with medium to fast currents. Their habitats are surrounded by riparian vegetation mainly composed of herbs, shrubs and trees and their substrate consists of sand pebbles and organic debris.


What to feed the Red Devil Tetra

Red Devil Tetras are not particularly fussy about their food; however, You should provide them with a varied diet. You can include a variety of live and frozen food such as bloodworm, brine shrimp and daphnia alongside good quality flakes and granules. It would also be beneficial for your fish if you gave them some spirulina and blanched vegetables occasionally.

How to sex the Red Devil Tetra

It is relatively simple to differentiate between male and female Red Devil Tetras. Males usually are slightly smaller than females and possess red colouring in their bodies and fins, whereas the females are larger and have yellow colouration in their bodies and fins.

How to breed the Red Devil Tetra

Red Devil Tetras are egg-scattering free spawners that exhibit no parental care. As a result, adult fish in good condition may spawn in a community tank, and small fry numbers may start to appear without any human intervention.

However, if you would like to produce a higher yield of fry, you will require a separate breeding tank. The breeding tank will need to contain soft acidic water with a dark substrate and dim lighting, and you will need to increase the temperature by a few degrees higher than their usual aquarium.

It would be better to make sure you have plenty of fine-leaved plants as a spawning medium and some floating plants to help keep the light subdued. It is also advised that you should provide very gentle filtration through an air-powered sponge filter, and dedicated lighting will not be needed as eggs and fry can be a little sensitive to light.

You can breed Red Devil Tetras in pairs or small groups; however, you will need to condition them with plenty of live and frozen food for a week or so before to encourage them to spawn.

Spawning usually occurs in the morning. The female will scatter sticky eggs onto the plants and substrate, where the males will then fertilise them. Once spawning has occurred, you should remove the adults from the breeding tank; otherwise, they will consume the eggs and the fry if given a chance.

The eggs will usually hatch between 22 and 26 hours later, and then the fry will become free swimming three to four days after that.

The babies will initially feed off their yolk sacs; then, after that, you will need to provide them with microscopic foods such as infusoria and Paramecium moving on to microworm or baby brine shrimp as they develop.

It would be best to keep the young fish isolated until they are large enough not to be eaten by the adults. You can then place them back into the regular aquarium.
