Tank mates finder

Pick a species to see every compatible tank mate, the ones that need care, and the ones to avoid, with a reason for each.

Good tank mates share the same temperature and pH, are too big to be eaten, and won't nip or bully each other. Our lists check every species against all 149 others. To check a whole tank at once, use the stocking calculator.
