How many Lents did you keep together Duanes?My lentiginosum did OK with the sailfins, although the current preferred by the rheophillic cichlids was a bit much for the mollies, and the mollies would occasionally get washed into the sump.
After a while I found wild type swordtails worked better, because they also prefer heavier water movement. They were also constantly dropping fry, which became snacks for the lents. The lents also were very fond of mosquito larvae
