Longfin Zebra Danio 4cm

Longfin Zebra Danio

The art of captive and line breeding has brought us many stunning ornamental fish, and the LongFin Zebra Danio is no exception. As a variation of the classic zebra danio, this fish keeps all the hardiness and activity that danios are known for, while adding beautiful, flowing fins that make it look even more graceful and captivating in a community aquarium. LongFin Zebra Danios are ideal for both beginners and experienced hobbyists due to their easy care and lively nature.

The LongFin Zebra Danio maintains the iconic horizontal striping of the standard zebra danio, with alternating bands of shimmering blue and silver running from head to tail. The difference lies in the fins, this strain has been selectively bred for dramatically elongated fins, especially the caudal and dorsal fins, which flow behind them like streamers as they swim. Their overall slender body shape and constant movement make them a fantastic choice for adding motion and flash to any tank. These danios are excellent in schools and look phenomenal when mixed with other colour varieties like leopard or gold danios.

Breeding LongFin Zebra Danio is relatively simple. Setting up a separate breeding tank with soft substrate, plants, and a sponge filter is ideal. While sexing can be tricky, females tend to be rounder and more full-bodied, especially when carrying eggs. A small group of conditioned adults fed with live or high-quality foods will usually begin to spawn readily. Females scatter eggs on the substrate or among plants, which males quickly fertilise. Adults should be removed after spawning to prevent egg predation. Eggs hatch within 24–48 hours, and fry become free-swimming soon after. Feed them infusoria, micro-worms, or baby brine shrimp during their early stages for healthy growth.

Tank Recommendations for your Longfin Zebra Danios

LongFin Zebra Danios are active, social schooling fish that thrive when kept in groups of at least five, though larger numbers are even better. A minimum tank size of 50 litres is suitable, with plenty of open swimming space and a tight-fitting lid. A well-planted tank with hiding spots such as driftwood and rocks is ideal. They prefer a pH range of 6.5–7.5 and temperatures between 22–26°C.
