Be careful, they will fight if you have two males, and then they also might kill off a female or two. I don't know about this androgynous thing, but I had 4 and 2 killed each other, and the other two have eggs, so I am assuming (and was also told by a LFS) that the dead ones were males.</STRONG><HR></BLOCKQUOTE>
The androgynous thing is true and you can prove it to yourself. With just 1 cleaner shrimp it will not produce viable eggs. Add 1 more and they will both produce viable eggs. That is only possible if they both make each other pregnant. Since there is a need for 2 to reproduce they are going to tolerate at least 1 other in their territory for that reason alone. That does not mean they will allow more than 1 other, especially if compitition for food is fierce.
