Brittanichthys Axelrodi Tetra (Brittanichthys axelrodi)

The Brittanichthys axelrodi Tetra is currently considered a member of the family Characidae; however, their actual taxonomic position is uncertain.

The Brittanichthys axelrodi Tetra is a very small, peaceful and fragile shoaling fish that is relatively rare and not commonly seen in the hobby.

These Tetras are perfect for the nano or well-planted aquarium. However, due to their size and delicate nature, it would be best to keep them with their own kind. However, these Tetras may do okay if you have a large community aquarium with only small peaceful species. Males can sometimes be quarrelsome with their own kind, but it is nothing to worry about as no actual harm will follow.

Brittanichthys axelrodi Tetra is a true blackwater fish; therefore, filtering through peat can be very helpful. In addition to improving the chemical parameters, peat's bactericidal effect also reduces the aquarium's bacterial load. Adding dried leaves to the bottom of the aquarium, such as Indian almond or oak, can achieve the blackwater look in your home aquarium, as can driftwood and alder cones. The water will gradually darken and will mimic the water in their natural habitat.

Currently, there is little to no information about the Brittanichthys axelrodi Tetra. However, these Tetras have transparent bodies and fins except for a solid red stripe that runs from the caudal fin through to half of the posterior part of the body and a thin black line on the top edge of their dorsal fin.

Feeding

In the home aquarium, the Brittanichthys Axelrodi 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 somewhat straightforward to differentiate between the male and female Brittanichthys axelrodi Tetra. Males appear to be much more vibrantly coloured than females and have bony hooks on their anal fin, as well as having a curved caudal fin when mature. In contrast, the stripes of the female are much duller than the males, and they lack bony hooks.
