Thanks , this pair is pretty funny they literally fear large clay pots so that was a no go. They love the PVC pipe though, it's the only thing they will spawn in other than on a piece of drift wood that's in the tank. They only used the driftwood once though they are hooked on PVC. Might be bc the female is super aggressive and feels more secure in the PBS than out in the open.
I might be two for two, my festae pair are lookin like they are ready to "do the deed" large pit dug female in the pit male guarding exterior area. Must be something in the water....
