Seeking advice on my clownfish

[Fishoguy]

new to saltwater marine fish, and am extremely paranoid and scared of loosing them, tank has been cycled for approx 3months 93l tank) have coral/Rock clowns & a sailfin tang, my concern is that it appears that around the female clowns anus it seems to almost be rotting away , looking abnormaly large in my opinion , and male clown has what appears to me a growth or has been bitten behind the right fin , any advice that can put my mind to ease to as what's happening would get me a good nights sleep . I've attempted to try upload photos not sure if they've uploaded still working out this great forum

I'm not sure if this happens with clowns, but many female fish sort of extend their genitals when ready to mate. Could be this? Maybe a clownfish breeder can pipe up...I do coral, lol...

I'm sorry, couldn't see the growth under the fin you are talking about....they look great to me!
