水草情迷

I got 10 燈魚 already for over a year.
I change a P20 for my 24" tank, 水流 increase but I think is very good.
but after a week 燈魚 突然 1 by 1 死去.... I did not change the filter material, NO2 all ok.
I saw the fish always shaking at the bottom all the time(swim against the water flow)... will the water flow too big so they can't sleep??
but other fish looks ok to the water flow.

check water temp
