got one argentus a few mins ago

RM8 quite big. waiting for more this wednesday.
to argentus and sabea owners:
Do they swim at the bottom of the tank often?
My tank is empty. no gravel or sand or what so ever. just the tank and one cave . I dont know if the water current/flow is too strong or what...but it looks like its hard for them to make a turn. swimming fine but turning like "cacat". once they turn, they tend to bend till nearly touch the ground...and when they swim, they are skidding like skating(on the floor)

or something. anything wrong with them? is the filter too strong? (its a 3ft tank)
