Clownfish weird behavior

[bachi]

I noticed this morning my clownfish acting strange. I don’t know if he has been doing this the whole time at night since I had him but I noticed he is floating on his side at the top of the tank at 5am.
I don’t know if he is sick, I saw one review on the same case I have and someone said it was overfeeding? but I don’t really think that’s the case.
If anyone can help, it’ll be appreciated

More info about you're system will help as well as a full tank shot with white light. If it"s swimming normally during the day or when it feeds it"s just "hosting" that spot and that's where it feels safe. If there"s an aggressive fish in your system it may be chasing your clown if it ventures away from that spot. If it is always floating back to the surface it may have a swim bladder problem.
