I’m in the process of putting together a mixed species Sunfish tank. One of the issues I have to consider is the aggression level of various species and why they are aggressive. Of course every fish is an individual with an individual temperament, but generalizations still help increase my chances of having a long term successful tank. There aren’t a lot of detailed care sheets compared to traditional tropical fish, but I have pieced a little bit together. Green Sunfish apparently are the devil, but Orange Spotted and Warmouths aren’t considered too bad.
What would be very helpful to me would be for those who have kept Sunfish in the aquarium to rate or comment on the aggression level of the various species. I would also like comments concerning the cause. Does it only show up as a breeding behavior, is it tank dominance, or are certain fish just psychopaths. Stereotypes usually exist for a reason, but I would also like to know if your opinions are based on the species reputation or if it is a personal observation/experience.
