You just remind me of a scene in Bad Boys 2, when Will Smith told Martin Lawrence that he seems angry..You know I have read quite a bit of your posts and you seem angry?
Chalceus are great fish to have and for the most part are very peaceful.. Mine does however, tend to get aggressive during feeding time when he tries to eat literally everything i throw in the tank, but it's nothing to really be concerned about. It's typically just a little chasing and bumping with an occasional nip. Mine is also 11 inches long so i'm sure that has something to do with it as well.
