.................................I really don't want to cause an argument that isn't here but aren't we working under the assumption that in Rams for instance, the "mothering" instinct, after so many generations of inbreeding is lost..............?????  I differ with that statement and conclude that the fish simply do not have conditions to their liking and will eat their fry until they have those perfect conditions.  For some rams it may be 83+ degrees as some of you have indicated....for my rams it is 78 degrees and all is well............and I have 200-300 some Rams around here (1/4" to full adult) as proof of 78 degrees etc.....after getting rid of an equal amount.  Some were pulled as eggs and some were left with the parents.  Some people say the mother does it all because of the likeness to apistos and some of you indicate that the male takes over at a certian point..................probably all true...............well, great...........no flames and we wil have a good weekend.  Are you folks all making plans for the ACA convention?
