Care notes

Long, flowing single-tail variety. Often sold as feeder fish but grows very large. Cold-water hardy. Excellent jumpers; lid required for tanks.

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.
