LOL...no..the male will be along side the female & as she lays her eggs, he would be fertilizing them at the same time. Only after that does the male scoops up the eggs in his mouth. This also only happens if the eggs are indeed fertilize. Otherwise it is abandoned or eaten.
Fish farmers take the eggs out of the males mouth for several reasons, chief among them the fact that if the fries were left to the free swimming stage in a pond with a 100 adult aros, it would likely end up as food. There is no set time to take the eggs out of the aros mouth.

they dont take the eggs out, they have to incubate in the males mouth, only after they hatch do they take them out.

Yes they do. As long as it's fertilize, whether it is incubated in the mouth or not does not bother the aro farmers. Also since pond inspection is a random process, they have no way to know at what stage the eggs have developed merely that the fish is brooding. When the fish is caught & they pry open the aros mouth, regardless of the stage of development, it has to be taken out, otherwise with the shock of being caught & all, there is a high chance of disaster happening. Trust me, we have witness many aro harvest & this is a normal occurance.

Usually in bare tanks that is well aerated. Tempreature doesn't seem to be a problem. Never seen the tanks with heaters etc.
