Clownfish lying in sand bed

[insane_blaine25]

I’ve had a pair of clownfish for a month now and one of them continues to lay in the sand bed in the exact same spot all the time. Clownfish swims swims to eat and seems to be healthy other than that. My first thought was ich or velvet but I’m not so sure since all my other fish seem happy and healthy. Parameters are all good and stable. I’m still new to reefing and am unsure of what to do. Any advice?

Is your other clownfish picking on it?

Is your other clownfish picking on it?

Not that I notice, I’ve never seen the other one go after it at all

Probably not velvet but it could be ich, flukes, or an oxygen problem. Is your tank getting proper aeration?

Some better photos would also help.

Not sure about the aeration but all the other fish are swimming normally and eating normally. Should I dip for flukes?
