I love reading a good ***** session on this forum. Its a good thing no one knows where the other lives or there could be alot of drownings reported :D. P.S. The tangs do need a very large tank to live out their little lives happily.
You have to sleep some time & when you do I hope that poor little crab crawls so far up your arse its remaining claw flashs at you every time you brush your teeth.
