This has been my experience as well. I found that constantly rotating the adults out worked fairly well. Lots of culling with these guys... expect a spawn every month numbering 50- 200 fry at a time. Parents will be agitated at other N. pulchers not of their blood line. If kept in a single pair older offspring will help look after the young. This can be misleading though as these fish pair off and break away from the commune to breed. If insufficient room is provided they will eat their young and relentlessly attack each other. I did not enjoy them but can see how a species tank could be fun ( but mostly profitable ), for awhile.I kept both species for several years and, as stated, the first breeding pair will likely systematically eradicate all the other fish in their territory; especially once fry are produced. I also wouldn't keep the two species in the same tank for the reasons already mentioned.

As was mentioned, beware of Brichardi Death Squads.
