I've been reading all of the posts and have determined that it could be a couple of reasons that my clown is swimming on its side at the top of the tank.
I'm introduced some spinach with their shrimp this morning and all seemed to enjoy it. (I have the 2 clowns and one blue damsel)
I turned up the O2
levels pumping out at the top. I usually have this going all the time but you can see by the pic that I've turned it up.
I do have a blue damsel that seems to RULE the middle of the tank, so I'm also wondering if stress and fear of the damsel is causing some weird behavior?
The little clown is still eating so that is a good sign and I'll continue to update.
