I have a colony running in one of my tanks, and I had noticed the same behavior. This was about 6-8 months ago when the fish where just coming to maturity. Since then I have had spawn from all the fish. I am still pretty new to the breeding aspect of fish, so take this as you may. ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@majordomo.pobox.com.
