I see it every day... People refer to this or that fish as being "mean" because it chases, harasses, or eats other fish.

"Mean" can be easily defines as: unkind, cruel, spiteful, or malicious. These are human traits.

If you place a school of Neons in a tank of large Angels, the Angels will eat the Neons. Are they being mean? Not hardly. They are doing what they were designed to do. A Neon is a natural food of an Angelfish. They eat Neons. If nothing ate them, the ecosystem in which they live would become unbalanced and everything would suffer.

This goes for everything found in nature. Everything has to eat something. It's all part of the grand design. If this seems unfair, mean, or unexplainable, might I suggest that you turn to your own personal system of faith/beliefs for answers on that one.

Some fish will bully other fish. These would be fish that come from a competitive environment (in the wild), or those who are solitary in the wild. Another fish is a threat. It could eat offspring, it could be undesired competition for limited food. They chase it away. In the wild, the chased fish may never return. In our tanks, there isn't room for them to just move on down the river, or whatever. So the two will encounter each other again and again.

Fish do not have the capacity for higher reasoning. All too often, people imprint human traits onto pets. This usually ends up with the people becoming frustrated with the pet. It isn't the pet's fault that a human expected more from it than it is capable of delivering.

Many people will keep, or try to keep, a pugnacious fish with more peaceful fish. Then they get angry with the more aggressive fish because it harasses the others. They call that fish "mean". It could easily be said that something "mean" has gone on here... but the fish wasn't the perpetrator.

Keep things in perspective. Don't try to make your fish into little submerged humans. They're fish. Appreciate them for what they are. If you want little humans, there are some very well proven methods for obtaining those. Just don't try to keep one in a tank.
 
Hi,

I totally agree with you. Its not the fish's fault, its are fault for putting incompatible species together.

That said, there are fish that will be more agressive in certain situations then other fish of the same species and gender. For instance you may have a betta that is just fine with tank mates, and doesn't chase them, eat them, or show agression. Put a different betta in the same spot, and he might show a lot more agression.

So calling a fish a "bully" might be anthropomorphizing the fish, but some fish will act in ways untypical of its species or emphazinging one characteristic towards fish not usually considered "targets."

I do agree that "mean" fish are not making some rational choice, and their behavior might be chalked up to their species, tank mates, and conditions. But I'd add that even with ideal conditions fish can demonstrate individual temperments that are not always predictable.
 
Yes, I remember reading recently about someone that had a fish that was supposed to be a peaceful fish with other fish but for some reason this fish had a problem with any fish that was added to the aquarium. They had him in a net so the other fish could explore the tank without being harrassed,but even being in the net for a time out so to speak, this little bugger was trying to attack the new fish even through the net. I really thought the fish was pysco and needed to be returned to the fish store. Maybe some fish that are supposed to be one way according to thier species and they are another way, like more aggressive then they really should be have some kind of mental problem.lol. I gues anything is possible.

Absolutely. Even domesticated animals can exhibit behavioral deviations, though more often than not these deviations are related to "life experiences" of the animal, or in other words, conditioning.

The fish we keep may have been raised domestically, but they are not so far removed from the wild as to be called truly domesticated.
