I lost track of the thread, so I'm sending this through again. I know it's an old topic, but it's like a Mike Tyson fight - you just gotta watch. someone raised a question about which fish (aquaria freshwater) is the most aggressive. lots of people chimed in. some folks mentioned hunger as motivational behavior, the particular fish, etc. i gave an example of an 18" snakehead shaking the willies out of and putting some new body piercings into the nuchal hump of a fully grown RD. So aside from the "it depends on the fish" comment, if you had to stake your life (or maybe your prized fish) on it, which would you say would be the "fittest," a 1 meter Red-line SH or a 1 meter Dovii?
