breeding neon tetras

[Ogertron3000]

thanks. can i put a spawning mop in the main Aquarium?

You can but depending what else you have in the tank it's very doubtful the eggs or fry won't get eaten.
Put the mop in another tank and remove the parents once they've laid the eggs and the chance of success will raise dramatically.
