you can see the pvc in my full tank shot. they once laid eggs on the driftwood behind it. they actually dug it out too. now that they are using the leaf im going to remove it and move itin about an hour. they dont seem to like the pvc for some reason.Hi have you ever use and PVC pipe in your tanks for them to breed in.then when u see the fry and they get close to hatching u just move the pipe to another tank.
