Here is the point: leave the pot alone in the same tank until the eggs hatched. Once it hatched, don't worry the baby can't swim right away for about at least 5 days, they will be in pot. You can just wait for the papa swim out the pot and then take entire pot to different tank , use your flashlight check the pot see how's those baby doing in there .... once they are freely swim .. you can remove the pot and put it back in old tank.
Remember make sure none of the babies are in the pot anymore ..
NOTE: while you are taking the pot out the papa tank, be careful, don't drop your pot back in tank .. hold it careful and slowly move it out of the tank .
