Shubunkin fins twitch fast

Hello,
I have a couple of Shubunkin's and I have noticed that they will
sometimes twitch their dorsal and pectoral fins extremely fast and then
swim fine. I don't think the current is the problem. It does not look
like it is pleasant to them.

Is this normal or is something wrong with them?

any explanation is truly appreciated.

thanks
dan

what are your water quality parameters, ammonia, nitrites, nitrates and pH? if those
are fine, and your fish are eating ok, then it is just something I have also seen
mine do. Ingrid
