Great piece. To buy Brazilian ornamental fish directly from the source, use B2Brazil.com (http://www.b2brazil.com), a comprehensive directory of Brazilian companies, including ornamental fish suppliers. B2Brazil.com is Brazil-based, and focused on facilitating business transactions between Brazil and the rest of the world. Be sure to verify the origins of the fish and compliance with applicable laws.

I haven’t had the time to read the paper. 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.

Interesting that the accompanying photo is a walleye, a prized fresh-water game fish, likely never held in captivity.
