Decent advice, but there are lots of exceptable filters out there. Do not worry about current/vibrations being a problem. That is a myth. These frogs need adaquate filtration so more is better where they are concerned.
That's why I said potentially stress them out. Mine loves her filter its one of her favorite places to float around is in front of it with the water pouring over her
