Hi I found this Panda Corycat-like behaviour in my school of Harlequin Rasboras a few days after a small shoal of Pandas (six) were introduced in the tank.

I don't know if it is a usual behaviour in the Harlequin Rasboras since I never noticed them doing this before the Panda Corycats took over the scene.

I'm not sure what you mean.........?

All I notice is that the current seems to be too strong for the rasboras and they're fighting it.

I agree, it does look like they're being pushed around quite a bit.

I don't know how Panda Corycat or Harlequin Rasboras act.

wow it sounds like a waterfall haha.

Yeah that's a lot of current

Ok this is the point: As I write this lines, the Harlequin Rasboras are behaving as usual, and swimming all around the mid-top part of the tank. They don't avoid that heavy current spot at all.
The Panda Corycats -which seem to be in mating season at the moment- when introduced to the tank, used to swim in zig-zag-like up-and-down-stream patterns. The Harlequin Rasboras, that has been living in the tank by themselves for a week or two and never displayed such behavior, began acting like this and I captured the moment.

I don't know if they behave like that usually, this is my first time with such fish. I am carefully tampering water parameters, slowly bringing down water hardness and alkalinity, aiming at pH 6.8 and KH 3dH; by filtering through peat since this is the Angelfish tank.

Their odd swimming is better appreciated towards the mid part of the video.

I'm not good with pics and vids, but I might get better with practice...

I agree with the current, its way too strong, especially with angels... not sure what your question really is though, rasboras and corys are both schooling fish if thats what you mean, the zig-zagging looks like they are being blown around by the current... maybe they like it

What's the flow rate on that tank?

I would have to say that the current is way to strong in the tank. But cool video anyway. Good job on the camera.
