Just noticed you also have loaches in with the Doviis. The loaches are quick and will survive and long as there is losts of decor. If you do end up with fry, eventually the loaches will eat most all of them. I had this happen with a firemouth pair in 120gallon planted tank with 14 assorted loaches.
it some times takes them a few tries to get it right, but dont worrie if all doesnt go well this time, im sure they will do it again s00n
