I have had some interesting spawnings in my tanks recently. Since like so many others, I have run out of tanks to move my fish into, I separated my male A. guttata and A. hoignei males from the females and their fry by placing a partition in their tanks. After several weeks, the female guttata chased the fry through the screen of the partition into the male's side. She then spawned and the eggs hatched a couple of days later. The interesting part was that the male was separated by about 8 inches from the spawning site. The hoignei did the same thing. I wonder how far the male and female can be separated and still get fertile egss?
