The American Cichlid scale is a guide for beginners to understand the aggression of their Cichlids.

1 = not aggressive
5 = medium aggression
10 = very aggressive

All listing are generalization of genus.

Please consider that the more fish you have in the tank the less aggressive your fish tend to be!

How aggressive your fish are can be a result of which fish is the boss of the tank.

Please get Your instructional Cichlid DVD guide for more information on Cichlid keeping!
