Altuvei Piranha

Serrasalmus altuvei is a small to medium-sized piranha from blackwater tributaries of the Orinoco in Venezuela, considered one of the most beautifully coloured piranhas in existence. Prime specimens display striking yellow-orange flanks with metallic iridescence that surpasses even Pygocentrus piraya in intensity.

Its blackwater origin means it requires very soft, acidic, tannin-stained water to thrive and display full colouration. Water hardness above 6 dGH and pH above 7.0 will stress the fish and bleach its colouration over time. It remains rare in the trade, commanding premium prices and requiring careful, experienced husbandry.

Piranha regulations vary; always confirm ownership is legal in your jurisdiction.
