I'm all for any kind of species of the month. I feel that it encourages people to take better care of their fish, if only for competitive purposes. For example, maybe someone has a flowerhorn but is a little neglectful with water changes and food quality, so in the spirit of competing with peers they up their knowledge and work ethic thus leading to an increased quality of life for the fish. It might not help all flowerhorns, but if it only helps one thats still something.
Also I really enjoy voting competitions that involve the fish, we get to see a lot of high quality animals that way and it's fun!
