I received some of Rod's at the end of Oct '07. Very small. They settled in and grew their 3rd stripe in a couple of months. The more mature clown I paired with a very mature female I have had for years. She was a breeder until her mate died. The new onyx quickly darkened up and they began spawning in May '08. Yes, the eggs were fertile. I have since removed the male and put the other Rod's onyx with the older female, since it remained in juvenile coloration and size. Trying to help it bulk up a little. Rod really does have some excellent percs, but there is bound to be some variablity.
