I'm throwing down. I keep seeing people say rivulatus get 12 inches, as though it's typical. I've had my share of mature, beefy male rivulatus and seen many more and I say 10 inches is more realistic, 9-ish not uncommon, and 12 an exception. How many of you have actually had one 12 inches? I bet not many. If so let's see them, with proof of size.
