How Contagiuos is Mouth Fungas?

[LeanneP]

I bought a coral beauty about 6 weeks ago who has been in quarentine since with mouth fungas. I have done a treatment of melafix and then a double treatment of both melafix and pimafix. I have waited 2 weeks and just added it to my main tank. Now I just realized it still looks like its lips are swollen and the cleaner shrimp went to it right away. I am not sure I will be able to catch it again without taking out my rock. I have read it is contagious and others say it is not. Anyone know if it is.
