Spawning would seem to start at 60 o F and would continue through the lower 70's. Although I would consistently find eggs laid in the indicated area, and very rarely at the bases of the plastic plants, I never witnessed egg deposition. A male and female would swim alongside each other, though I never observed eggs being laid. Freshly laid eggs were notable for their strong adhesiveness when collected. Unfortunately, any eggs set aside all fungused.
Indications are that sand rollers spawn on rocky bottoms as do their eastern cousins the troutperch.
Currently I am making further attempts to spawn the species.
