Comparing Aggression Levels in Jack Dempsey Cichlids Based on Variation of Haitat Structure

, 2013
Jack Dempsey cichlids, Rocio octofasciata, are native to South America and known for their aggressive behaviors. These fish are popular in freshwater aquariums, but can act aggressively towards other fish.

Habitat structure directly affects aggression in convict cich-lids Archocentrus nigrofasciatus

Current Zoology, 2010
Aggressive behavior can be an important factor in determining how animals use and divide space and resources. Previous studies have shown that aggression in fishes can be influenced by a variety of factors, including water temperature and resource levels.
