The question that comes to my mind is - given that Nothos are annuals, and the eggs have to go through a long period of incubation, why would you want to do it that way ?
Nothos will spawn in bottom mops but transferring the eggs to peat moss for incubation is just too much work.
the soft substrate of their pools in nature and peat moss comes closest. Nothos will also eat their eggs given half a chance and they would be more exposed in a mop and, therefore, more susceptible to scavenging. It is just a very inefficient way of spawning Nothos.
Nothos will spawn just about anywhere, even on the bare glass base of a tank.
