Not uncommon especially for first spawn..It could take several tries
I offer a almost vertical piece of slate in the location they have picked to be able to remove slate. I have even cut 3X6 inch pieces of slate and hung from rim of tank ang they laid on it..
They should lay every 7-14 days now ,IF they didn't just move them...
Spawning fish are full of tricks...
