Two Questions

[Miles_hot]

1) how do you sex Tigers?
2) What is the minimum size tank for a pair of kribs who are breeding if we wanted to keep and grow on the fry?
Thanks

1. Male tiger barbs have a red nose and a bright red line on the top edge of the dorsal fin; female's dorsal fins are plain black or black with a clear edge.

2 20g IMO

i would say no less than 25 G for the kribs
