Concerns about Black moor

I have a black moor and a fantail currently in a quarantine tank. I noticed
that the black moor is not a very good swimmer compared to the fantail.
Specifically, the current created by a penguin filter and airstone poses no
problems to the fantail but pushes the moor around. If I lower the air-flow
rate from the airpump, the moor can swim without any problems at all. This
concerns me because the main tank is larger, but has two bigger penguin
filters, a bubble wand and two airstones (although their arraingement may
offset each other somewhat).

Is this inability to swim with a current a sign of weakness or the norm for
this breed?

The water parameters are excellent, ph 7.2, ammonia 0, nitrites 0, nitrates
5ppm, 75deg F.

Turn it down and let him "recover" for a bit. Turn it up slowly and see if he
can
adjust. My Moors seem to do ok with strong currents, and actually enjoy swimming
against
it.
