Care notes

Also called Denison Barb. One of the most stunning freshwater fish — brilliant silver with red lateral stripe, yellow dorsal stripe, and black-and-white forked tail. Critically endangered in the wild. Active schooling fish; needs 5+ and plenty of open swimming space. Prefers cooler water.

Check the whole aquarium. Tank size alone does not establish compatibility. Confirm adult size, water overlap, social grouping, territory, diet, and the individual animals before stocking.
