i know a post was posted about how to see whether or not they are male or female when you turn them upside down but if i am looking for one in the petstore i cant exactly take them out myself and check so is there an easier way to see under them in the petstores or to tell them apart or do you think the petstore people will do that for me. thanks for any help
P.S. the fish not including the tails are about 2 inches so they are smaller fish but i tried looking with larger fish and couldnt see a difference eather
