Rather Odd Behaviour...

[The Taffy Apple]

Evening all, just i'd share a little something with you that i noticed last night.
It's not an issue or problem at really, the tank is very healthy and mature...

I added half a dozen R.N Tetra 9 days ago and after observing the tank i noticed one of them (quite possibly the smallest one) swimmming DIRECTLY below one of the older Cardinals, mirroring very move, twist and turn. Think of those parasite sucker fish commonly found on sharks ,just like that !!!! It done it for the whole 15 mins i watched the tank yet hasn't done it since.

Has anyone else seen such behaviour between these two types of Tetra, or any other species of fish for that matter?!?!

I recently adopted a 4ft tank that came with a few different fish. It has one black molly and it does the same behaviour with my blue gourami. Interestingly it doesn't bother the other two orange gourami; just the blue . The previous owner told me they had this odd connection and within a day of setting the tank up they starting doing it again
