I have two fish, Very unlikely mates Yet they seem to have a very strong bond. They always spend the day rubbing against each other & the smaller one more than the large seems to get emotionally down when they are spilt up?!?!?! Do fish feel/think this way? Do they make friends & miss each other & what if they are not fish to be known to be together & yet act this way? Before I tell you what kind of fish they are I want some input on the mental thinking of fish in this matter?
