I have purchased 2x 2 inch bala shark and 1 angelfish. At the moment they are in my interpet 120 litre (30 gallon) fish tank, its temporary they will be moved into a 200 gallon tank shortly. But my question is, is that im using the 3 action filter that came with the tank and realise both fish like different levels of water current. The bala sharks are doing great and enjoy swimming against the current, but the angelfish appears fine and is acting well though does like to stay out of the current. I heard angelfish dislike current silver sharks like current so what should I do? At the moment I'm sticking with this filter as the angelfish doesn't look too bothered. Anyway I would be very grateful for an answer, thank you.
