moving all the fish into one tank. nuke the empty tank . then start moving fish back into other tank when water conditions are where they need to be! and get a water test kit
The new fish, has ticks(swims and twitches, involuntarily) but seems alright other wise.
My friend got up some pictures, here is the severum he's the only one who has symptoms and is really able to be photo graphed, you'll also see the syno in some photos he's a mess as well but not so photogenic.
Not every fish looks like this most of the ones with open sores died and got tossed already. He has a little fin rot starting in there too.
I never treat water, all my tanks got changed only 3 went bananas. I've never had a biofilter crash from a untreated water change. All I'm saying is I don't think that water quality effect my 100 gallon tanks, they have been pristine for a while the 110 was questionable for sure but the 100 stack was two solid tanks. If water quality was an issue then this would be settled already since these tanks have been getting 40 percent or more changed daily for 4 days now(friend just changed them for me today.)
Quick cure and snails where different tanks. I treated the 110 gallon with quick cure when the disease kicked in. Then when it didn't work and it jumped tanks it was apparent that was not gonna do anything. So snail tank and quick cure tank are different tanks.
Thanks for all the ideas guys. I'm sorry I'm flippin out but as you can see things aren't going well. These photos are from yesterday I'm told he is even worse now.
