I've heard that they don't get along well together for some reason. Really, I know jack about them, just love their colors, plus they are different 'dithers' compared to silver dollars. I would much rather they be a shoal or school though if possible. What size of tank would I need to do this? How many would I need also? I don't wanna waste my money and get a group of them only to have them all end up killing each other. Any and all help would be appreciated!! Thankz!
