2 Green Tiger barbs.
Lip Locking barbs, furiously pushing at each other, what is the meaning of this?
They meet on the left side of my tank, swim in circles, then BAM, they are at each other's lips and they are fighting.. this is very interesting... They push against each other, and the one who is able to push the most gets a nip at the stomach, this goes on for a while, and than they stop to chase around some other fish, and they are at again..
Swim in circles, lip lock, push, bit. Repeat..
I just notice this happening today, what could they be doing? it is rather entertaining to watch, but i hope they don't kill each other..
