Striolatus Pristobrycon

Pristobrycon striolatus is distributed across the Orinoco and Amazon drainages and is distinguished by fine horizontal striations along its flanks that are visible in well-conditioned specimens. Like other Pristobrycon, it occupies a dietary middle ground between strictly carnivorous and omnivorous feeding strategies.

It is more inclined to school than most piranha relatives, and a group of five or more individuals displays cohesive, natural behaviour. Less aggressive than Pygocentrus or Serrasalmus, it can be considered for careful mixed-Pristobrycon setups under the right conditions, though species-appropriate caution is always advised.

Piranha regulations may apply; verify local laws before purchase.

Water: 24-28°C, pH 5.0-7.0, soft to moderately soft; blackwater tannin supplementation recommended. Tank: Minimum 300L for a school of 5; driftwood and floating plant cover; secure lid. Feeding: Omnivore; varied diet of fish fillet, invertebrates, quality pellets; accepts a broader range of foods than pure piranhas. Breeding: Group-spawning species; rarely documented in captivity. Compatibility: Best kept as species group; less aggressive but still requires careful management; verify local piranha restrictions.
