mine are still little 6" but a month and a half ago i got them at 3" they seem to be very friendly to the other fish, but skittish of outside the pond activity. they dont bother the goldfish that are in there with them. i also have never even seen them eat a rosy red (i keep the pond stocked with them for the Crenicichla Venezuela.) they have schooled up with my pair of 12" oscars that are in the pond also.
