Care notes
Single-tail variety; grows very large. Better suited for ponds than indoor tanks. Cold-water species. Can live 15–25 years.
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.
