Signs of ICH?

[anthonyhdo]

there are no visible signs of ich on my fish, but I see my fish sometimes dive into the sand and rub their bodies in the sand. Could this be a sign of ich? some of my fish midas blenny and clownfish.

any advice is appreciated.

Evening,

there could be a few reasons for scratching. If the fish is new or there are new additions in the tank there could be ich or flukes. Could also just be behavior. i would just keep any eye on them. If scratching is heavy or other signs developed, then there may be an issue.
