"kribs do the darndest things"
Put 1st fish - small skunk loach in my 50 g 2 days ago. Wouldn't come out and hid all day. Added a pair of moderately aggressive kribs today both about 4-5 times his size (think the female is pregnent) and for the time being the loach is chasing them around the tank. Don't expect this to last very long haha.
