Can i assume Pinima are usually aggressive then?
He is pretty much outnumbered and outsized but can easily dominate 50% of the tank if he loses his temper, the larger Pinima is actually great and also falls victim to the aggression.
It is the one who is blind in one eye, i did wonder if this maybe was the reason but i had never heard of them being aggressive.
