Water Current

[hawil]

Does swordtails and platies do well in high fast water currents?
My tank is 15 gallons big and has a Resun Stream Filter BS-40E

My 3 swordtails goes at the end of the tank where the water current of the filter ends and they go from bottom to top or vice versa nonstop but usually it is only the female swordtails (the other is pregnant).

I do WC 2x a week
The fish are healthy and nothing is on their skin/scales
They eat well
Water is very clear

I know the water has no problems since the juvy platy is staying on the other side of the tank just below the filter and goes around the tank normally.

So, is this a normal behavior of swordtails?

Questions about water parameters, I can't answer any of it because kits doesn't exist in my country. Thanks.

This is what they usually do. View the video counter clockwise.

That's quite normal; probably a bit of arguing or mating going on, that's all

But both of the females are already berried

Is that how they play with water currents?

Livebearers generally don't care if the females are already pregnant! That is how they 'play' in the current too, yes. I don't think you have anything to worry about.

Is that so? I just remembered the day when they all first met! Man the male was always on the go!
Cool! That is good to hear! It stressed me out for a while really.
