I just noticed my cories r missing their barbs. Should I be concerned ?
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.
