Hi cntlaw! We've asked Dr Kisup Lee in S. Korea.

The blue-ringed BFS could be K58 or K67 since their coded bands have disappeared since 2009 and 2010 respectively.

We'll try to find more previous sightings to compare their faces. But as far as we know, both of them have thin yellow eye-line, making it quite difficult to distinguish.

Dr Lee said they've changed to stronger bands from K81, so far they works well and haven't dropped since then.

Hope it helps =]
