Comments on: You Wouldn’t Like Your Fish When They’re Angry! http://blogs.discovermagazine.com/discoblog/2011/09/28/you-wouldnt-like-your-fish-when-theyre-angry/ Quirky, funny, and surprising science news from the edge of the known universe.

However, this stuff is well known from empirical evidence to hobbyist fishkeepers. In particular, the fact that aggression is higher in smaller tanks and putting plants or other objects (supposedly to limit the visive contact between competing fish) lowers the levels of aggression. Also, the paper is on Amphilophus citrinellus, a territorial cichlid. It would be nice to see if the results are the same with other species such as Characids (which go in groups and don't display the same territorial behaviour) or other *teoretically* more peaceful fish.
