Hey all. I was wondering if anyone out there could tell me if my saum is a male or female. I bought him when he was only a couple inches and he's now almost 7" about 2 years later. I thought he was a male because he is quite colorful and large relative to his tankmates at the lfs but now i'm not so sure as he is almost 2 and doesn't really have a nuchal hump. Anyone?
