Black Line Tetra (Hyphessobrycon scholzei)

The Black Line Tetra is a very peaceful species that makes an excellent member of the community aquarium and will get along with most species of fish. However, they will not compete well with very boisterous or much larger tankmates.

The Black Line Tetras are quite hardy so are therefore suitable for the beginner aquarist. These fish are a sociable schooling fish so you should house them with six or more of their species.

The Black Line Tetras ideally should not be kept in an aquarium with soft plants as they will happily consume them so if you do require plants, it is recommended you only buy hard plants for this fish.

The Black Line Tetras primary body colouring is silver that displays an obvious defined black line that moves horizontally along the middle of the body hence the name. This fish also has a dark splotch visible on the tail fin, but all other fins are transparent.

Feeding

In the home aquarium, the Black Line 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

Unfortunately, it is practically impossible to differentiate male from female Black Line Tetras. However, sexually mature females tend to be slightly larger and noticeably deeper-bodied than that of the males.
