You're gonna have to be more specific! :P But all the blue/red ones are from petsmart. Willing to bet three are spawn sisters.
Yellow from the LFS, same withe the heavily iridescent girl. Iridescent lady is no longer with me sadly. Oh, peachish girl is from petsmart too.
As for the shrimp. It's a giant fan shrimp, 2" + Really it's only been disturbed two or three times, once by the pleco, and once by me. I'm sure my alpha has gotten too close, but they are both the same size. And it sticks out of the way.
As it is I'll probably end up tossing in some of my RCS, I've got a tank that has dozens of baby shrimp growing up rapidly.
