Australian Research Shows Warmer Water Raises Aggression In Fish

And damsels need more aggression?...

"New research in Australia has shown that coral reef fish can undergo radical personality changes in warmer water, work that suggests climate change may make some marine species more aggressive. Experiments have been conducted on two species of young damselfish on Australia's Great Barrier Reef, which have shown that water temperatures can alter a fish's behavior."

"If you are an individual fish swimming around the environment and you are active all the time, you are going to be visible and encounter predators more than an individual that is inactive, right, and so these activity level differences and boldness level differences in relation to temperature are going to have effects on risk to predation," he said. "And as a result of the warmer water temperatures animals were more active and they were more bold in the face of predators and that essentially got them killed."

temp and aggression

I totally agree. I repair lobster tanks. The temp is usually set at 42-48°. When the compressor cuts out and the temp gets above 50° they get nasty to one another and kill each other. The resulting rotting lobsters that are not removed causes the tank to crash. Also they start to die also when the temp gets above 55°.

Would this have anything to do we an increesed matabalisam(sp?). It would seem that if the fish needed more food to sustane, then it would become bolder and more agressive.
