Picked up a couple belly crawlers from the LFS about a month ago. My first pikes. The smallest (3.5") and largest (5") in the tank hoping to get a pair. However, it looks like they are both males. They are about 4" and 6" now and neither have the dorsal spots. Am I correct in assuming they are both males? I'm going to go back to the LFS and see if I can pick out a female. My other question is, how large do they have to be before the females show the dorsal spots? Should they be showing at 4"? Any advice is appreciated.
