That's for sure. My 5" con currently runs my largest community tank, which includes a jag and a 13" oscar (I know that O's are wussy's for their size, but it's funny to watch a 13" O throw down and lose to a 5" (probably 4.5") con.
That is a decent nuchal hump forming. My con has a big one right now, since there's a female Jade Eye he has his eyes on. She's moving tomorrow though, so no hybrids.
I saw a normal old male Convict with A HUGE cranial hump once, I was surprised they could develop such a thing.
Also I noticed old male convicts teeth begin to protude past their lips. They are already cool looking little fish but the seem to transform into something even Better.
