levels in your tank. If that's not it than it could be a toxin that leaked into your tank. It could be as simple as bad dust particles or lotion or spray.
True it could've been that. But the last clown ended up dying as it wouldn't eat. I moved it and my goby to a quarantine tank and observed them for a few days until the clown died and the goby is still doing fine to this day.
I put oxygen stones in the display tank and that didn't have any affect (They seemed better at first but after 36 hours with the stone in the tank they started showing the same symptoms) and I have a lid on top of the tank. Could that have a great affect on oxygen levels?
There are quite a few snails in there as well. I'm not sure if they brought something with them when I put them in the display tank or not?
At any rate the tank will have no fish in it until the end of November when I can make sure whatever was infecting the fish is no longer in the water.
Is that the route I should tank?
Also the fish store I got the fish from ended up letting me exchange the dead fish for a new one (haven't picked it up yet). I got some seachem medicine while I was there, paraguard and cupramine I believe. Which one should I treat the clown with first when I put him in the qt?
