This one isn't quite full grown, but it's 10 years old. It's a rescue that lived it's whole life in one of those square aquariums. Bad enough, but much worse when you realize that it lived in there with its three siblings. I don't keep the rescues, but because I'm a big fan of the aberrant scute patters, I'm keeping this one.
I know, I know. This technically doesn't match any of the criteria, other than being an aberrant shell pattern. Little Brendel here is 9-10 months right now and has 1 less scute than normal.
