AS per the request of the CPD guru, I've started a thread to keep you posted and myself to keep track of my Breeding efforts.
i have kept CPD for a long time after getting one for free from my LFS (last one they had about 4 years ago)
Over that time I've bought more than i thought i ever would, but never got a successful breeding program happening. At one point i had 40 and never saw results (although they were in a display tank and i wasn't giving breeding a real concerted effort)
