Mating playing or agression ??

[Fedex3d]

My 2 bala sharks are the only 2 in my community tank. They are only about 4" long so they are far from mature. About 2 or 3 times a week they start doing a dancing ritual where they swim together as if joined at the side. I know they are too young to be breeding. What are they doing ??

If you dont see any visible signs of wounds then i would have to say playing, what size tank is it?

They are in a 29g right now but lm gonna start cycling a 125g next month & move them into it. I think they are just playing & they seem to be very happy fish
