Hello Bb...

If you have a substrate or decor with potentially dangerous edges, this could possibly injure your Corys. Corys can also get stuck in plants or roots and the barbels can be injured and die off. So, that would be some things to check. In pure water conditions, the barbels can heal and return to normal in a month or two.

I would wait for someone who is more experienced to comment, but I think the substrate could have something to do with it

I had some lose theirs, it happens in gravel.
Now they are in sand substrate and very happy with all their barbells and also love to sift sand through their gills.

What are your parameters? Many times a high amount of nitrates can cause the barbels to diminish.
