Yellow Congo

Alestopetersius caudalis is an African tetra in the family Alestidae, also known as the Yellowtail Tetra. Its natural distribution lies in the Congo basin; that native range should not be confused with the origin of this tank-bred stock.

In aquarium keeping, it is valued as an active shoaling fish. Mature males develop more pronounced coloration and extended fins, while females are generally less ornate. A reference maximum of 6.2 cm total length is reported in FishBase; the catalogue's 4–4.5 cm measurement describes the fish offered for sale.

The October offer is priced per individual fish, with a minimum of 45 fish. Use the MBI offer code to identify this listing when building an inquiry.

Maintain in a stable, established freshwater system at approximately 22–26°C. Provide open swimming space alongside planted or sheltered areas. Keep a shoal rather than an isolated individual and avoid cramped conditions, which can increase conflict between displaying males.

Aquarium husbandry guidance describes this species as generally peaceful but easily startled. Select comparably sized, non-aggressive companions. Offer varied appropriately sized aquarium foods, including a suitable dry food and small frozen or live foods; include some plant or algal content. Confirm the food already accepted by the arriving batch.

Match the supplier's holding-water conditions during acclimation. Published pH recommendations differ, so a single universal pH target is not specified here.

The October catalogue lists 45 fish per bag and a maximum of 8 bags per box for the 4–4.5 cm option. The minimum order is one bag, equivalent to 45 fish. These are catalogue packing figures for this offer.
