Leandrites cleaner shrimp, gotta love these little guys.

My fav shrimp species! I found my first community of these guys in the late 70s at a reef called kirra reef and there was no name or info on them at that stage, so it was a cute shrimp and i learnt heaps from them,lol, anyway over the years i see heaps of them and never get sick of these and they are the only true cleaner shrimp.
In this video of a couple of mine, the larger always becomes either just female or a herm like red lines and pepermint shrimps, that i do not know, but in this video there is a male that acts as if it is not game to become a female, the old girls are vey bossy and run the entire community.
