I have a quesiton about the social behaviors of Tetras. I have three tetras that were the first fish in my tank. Apparently, rather than being a schooling fish as I expected they seem to pair off. So I have two of the three which have paired off and stay together all the time. The third is a loner.
I'm wondering if it would be wise for me to add a 4th tetra for the loner to pair off with and if I were to add a stranger would that be likely to even happen.
