I've read that the difference is in size and body shape, with males being higher-bodied. Any truth to this? I got a couple of these guys a while back, and they're now 6-7". Two pics of each, and they appear to be males, but I'd like the opinion of someone who knows better than I do. If anything can chime in, I'd be most appreciative, so thanks in advance. And yes, I know I have to trim the Anubia
