Sold at 5 cm, but it grows to 25 cm and lives 20 years. It must be kept in a group of five or more, and at that size even 250L is cramped. Unusually prone to ich and sensitive to copper medication.

Good tankmates

No eating or bullying either way, with plenty of overlap in temperature and pH. Fish that swim at a different level come first.
