About

Myleus setiger inhabits river systems across the Orinoco and Amazon drainages and is distinguished from other Myleus by subtle morphological features including fin ray extensions in large adult males. Its colouration is a warm silver-bronze with scattered faint spotting and attractive fin tones.

As with all large Myleus, it requires substantial space and plant-based nutrition. Its relatively peaceful disposition and adaptable nature make it one of the more accessible large Myleus for experienced keepers. A group of five or more creates a cohesive, impressive school.

Not restricted under piranha legislation.

Care Guide

Water: 24-28°C, pH 5.5-7.0, soft to moderately soft; clean, well-oxygenated water is important for this active large species. Tank: Minimum 600L for 5 fish; strong filtration; open swimming space; robust décor. Feeding: Herbivore; spirulina-based pellets and flake, blanched vegetables, and occasional fruit. Breeding: Egg-scattering species; fin extensions more prominent in breeding males. Compatibility: Peaceful; suitable with large South American cichlids and catfish.
