Yeah, well I once saw a clown host in a trailer out behind a circus tent
Brad makes a good point though, as both my hammer and torch are large enough, with spacious enough branches that the clowns and perc do not bother them.
I would also like to add that: I feel IMO that all clowns and and pretty much any other fish that you chuck into a tank will always have a natural fear of predators no matter how close or not the tank is to there natural surroundings
