Does anyone here have a mature turquoise severum? How did the fish color up over time? I purchased one from Petsmart back in May. It's still only 3 inches long so I think it still has it's juvenile colors but I'm starting to see the blues/greens coming out in it. Just wanted to have an idea of what it will look like as an adult, especially those who might have bought one from Petsmart. Pics would be great too. Thanks.
