I have a sexy shrimp in my 90 and he is always on my Ricordea. When I put him in there I put him right next to it and he has been on it ever since! I have only seen him off of it twice and both times he was right next to it.
Very cool. the nems and shrimp. How big is that nem in the pic? I'm guessing a few inches across.
Though, I dont have any nems as of yet, and for some reason, ricordias havn't taken well to my tank. Though, Rodactids have done quite well and even split. I will have to look into getting some sexy shrimps in time. Though, I would be worried the the Reef safe wrasses I am looking at getting may eat them. Who knows.
