That's not necessarily true. The male can still find the eggs if he looks hard enough.
The problem with substrate tanks is unless you have tons of plants absorbing ammonia, etc from the water column the wastes will build up and stunt the growth of the fish. With an NPT and substrate its either go big or go home, its not something you can go into half cocked.
