Yes I have them. Got them from this site. I have 4 in my 55 reef their also known as saron shrimp. I have not had any problems with them so far. I have had them for about 3 months. They are neat but kind of shy. Mine will change color depending on the lighting and whatever they are sitting on. I have seen mine bright pink to a dull brown and gray. They have little dots all over their bodies and mine are about the size of a cleaner shrimp.Hope this helped.
They are very shy and will stay in the rocks as much as possible...Unlike my flame shrimp I can entice him out in the open by feeding him through an eyedropper using frozen or live brine....They do change color depending on lighting etc...as someone earlier stated. I also bought mine from this sight and have one in a reef community 55.
