As my male and female Blue Throats grew to over 6", they both began to display behaviour called "stereotypy". This term describes any behaviour that his repeated constantly. You've probably seen this in caged bears/cats in old zoos. In this case, it was repetitive swimming pattern back and forth along the wall of the tank. This behaviour would only be interrupted at feeding time.
In my case, the male Trigger actually began to wear through the acrylic of the tank wall.
Even in my 400 gallon tank, it was just too cruel to watch this fish pace and I have donated him to the local public aquarium. I am hoping that his behaviour will change in their 12,000 gallon system.
