ive heard from every web site and person ive ever talked to sayin that they hate their own species, and are better left one per tank. well today at the fish place the guy said that they hate anything that is even resmbling the same shape! is this true?? what do you think would happen if i were to put one in with 4pictus and 3silver dollars?? and what have you gathered from past experiences from rainbow shark?? im curious!!
