Cloves types, questions about being nuisance coral!

[miserkris]

Can blue cloves smother other corals or grow overthem.if so what corals are they.can any thing get stung by blue cloves?

Are all cloves the same, when it comes to reproduction...i have green, blue, brown cloves.can they get sexual and send spores to other parts of dt?.......and start new corals elsewhere?

Thanks
