Care notes

Selectively bred for bold red-and-white banding. Requires soft, acidic, very low-TDS water (RO + remineralizer). Temperature-sensitive; best with chiller in warm climates. Graded by pattern intensity (SSS highest). Very rewarding but demanding.

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.
