Oh I'm a long way away from the badge. I'm facing the problem now of raising the fry and trying to stop the parents from producing even more fry. So until I get rid of these I won't be able to move on to the next species. What's in the tank? Lots and lots of platies and bristlenose babies. And quite a few guppy males. The platies hassle the BNs, taking little nips at them. They even take nips at the adults.
