Question About Botia Striata & Botia Dario

[Barracuda518]

I have B. Striata and B. Dario in the same tank. I have noticed the B. Striata chase each other around, a lot actually, and just thought it was playful chasing. No damage being done. But I have noticed that the B. Dario has now joined in on the fun and they all chase each other around. They dont chase any other fish in the tank, just themselves, but they do it all the time. Is this normal? I havent seen any differences in them (they eat as normal, dont ever hide, etc.)

Thanks in advance

Just making sure because they sure get their excercise chasing each other around the tank

Thanks
