They sure did fight the first day they were together. They seem to have worked things out since then. They each have a favorite spot, but they do hang out near each other at times.
The "female" is at least 4-5 years old. Possibly older. I do a poor job of recording when I add someone to the tank...
The new male will sit in his log and fan the water with his fins. That is something that the other has never done.
Guess I will wait and see!
I really doubt they care if I am male or female.
As far as they are concerned there are 2 kinds of people who live in this house - ones that feed the fish (me!) and the ones that don't (everyone else).
