UPDATE: I just watched Elvis (baby) and Emma (CT female) have a flare-off. I could clearly see that Elvis has NO beard at all. It also got serious stress stripes and acted super tough. I think it wants to be dominant to Emma, but being half her size, it just had to act tough. XD
So, I'm leaning even more toward female now. I actually hope it's a girl. I was gonna set up a 10-15 gallon sorority tank this summer anyway. Now I have less girls to buy :D However, I won't put Elvis into the sorority until I'm SURE it's a girl. But that's not until May at the earliest, so I think I should know its gender for sure by then.
