My clownfish is currently swimming on its side at the top of the tank, my other fish are doing fine so I’m not sure what’s wrong? I’ve got an air stone that runs 24/7 and a canister filter. Now I did have a total brain fog a couple days ago and forgot to turn the filter back on after switching it off while cleaning the tank and doing a water change. It was off for about 24hrs before the water turned cloudy and I realised what I’d done. The water is clearing up now but the clown is still behaving like this. What do I do?! I’ve done a water change and checked parameters, the pH needed raising slightly but other than that everything is fine??? The bubbler stayed on the whole time which is why I think I didn’t realise the filter wasn’t running. The fish isn’t really gasping but it’s staying at the top and side of the aquarium.
