I have been growing out a group of green terrors for the past 5 months or so in hopes of getting a pair. Of the five, three are male two female. The two largest males are roughly 5.5 - 6 inches, and the other three are all about 4 inches long. The last male is a runt. Anyway, no pairing yet. I think it might be a while yet before the females mature. The two big males are probably pretty close and have become a bit aggressive toward each other. Enough babbling though, pics. 
This is the #1 male. He has been dominant since day one.
And this is the #2 male. He isn't very aggressive and is actually a bit larger than the dominant male.
