What’s wrong with my clown?

[ZachariahBeanzz]

I just walked into my room, and was looking at my tank, and couldn’t see my clownfish anywhere. This isn’t usual as he’s very active. I looked everywhere and found him at the bottom of the tank breathing heavily, and looking like it has bruises? I don’t know what’s wrong, it was fine a couple hours ago, but now it’s on its side, not being able to swim well, and seems almost unresponsive. What’s wrong?
PS. My parameters seem fine, all within normal ranges, and he’s the only other animal in my 20g AIO.

post a video under white light, what the parameters are and other tank inhabitants. if there's another clown, she may have beaten him up. if it's water quality, your parameters will show that. if it's disease, the video of breathing could be key to diagnosing.

Unfortunately, the little guy has put himself in close to the rock work, and I’m unable to get pictures or a video. He just looks very red/brown over his body (it’s a Wyoming white). As for another inhabitant, he actually killed the other clown that was in there a couple days back. My parameters seem fine. Ammonia: 0, Nitrite: 0, Nitrate: 20-25ppm, pH: ~8. I didn’t think I would need to measure anything else, but if something else would help, I can quickly test for it. Also, it does seem to be that the clowns breathing faster than normal.
Thanks for your input!

I think you will really need to get a video for the fish medics.

Take a look at this thread then, does it look similar?
