I second everything Naomi said about Amano. They are awesome! If only for their difficult reproductive cycle, they would be the best thing ever to have happened to planted tanks hobby. All my females carry eggs from time to time and yet because of their (what's the term for dual environment?)change of habitat from young to mature, they are hard to propagate. Otherwise, I would get as many as I can and put them in all my planted tanks. They also go about $2 a pop here in Houston. Cherry is like $3 per shrimp, which is 'fair' I guess, but I totally agree in their somewhat less efficient work ethic Amanos work harder.
