Seems like my fish want to leave tank kind of a tiny bit. My yellow watchman goby is swimming freely and towards the top. He’s been doing it for weeks. I also checked parameters and everything was completely ok. I aimed my 1 powerhead towards the surface for more agitation. My corals seem completely fine minus 1 gsp but it is just closed and partially open. I switched out filter pads as well maybe that might help. My puffer seems to be looking at reflection and clown seems ok along with my cardinal fish who is chilling in corner.
 

Sorry for the late response!!! Had a family dinner
 
could you include a video of the watchman swimming to the top by any chance?

For some reason my videos aren’t posting but this is a picture he’s hovering in place
 
Oh got it, I’ve had watchman’s do that kind of thing before I really don’t know why they do it but mine have never seemed to be wrong after or before doing it
