fish dying, white skin peeling off, please help!

  • We are currently upgrading MFK. thanks! -neo
What a bummer..

Happens to us all.

Has happened, will happen again...
 
I was going to put hte cat back in the big tank and salt it, would this be bad for the tank. I dont want any of the sick fish with any of the others in the clean tank if at all possible. Will salt hurt the cat and how much do I add if i do it with him in there. luckily this cat was the favorite of the bunch, least expensive of all who died but favorite none the less. If it would be best to leave him in the other tank since he wasn't loosing his slime coat I can do that as well.

Thank you so much Miguel and others for your help, it means a lot.
 
Do not salt the cat...
 
Also looks like I will be buying an adapter for the sink down stairs for my python since I already have one for the bedroom but the hose won’t reach. This happened once before the first time I did a water change when it was cold using the hose. I caught it the first time and was able to add a lot of hot water and all fish revived. I think this was just too fast and the hot water heater was out of water so I just grabbed them and put them in a hot tank so they were shocked twice. Would you think whatever got the slime coat off my fish is in the water column or just on the individual fish. I want to be sure to clean the tank out so no new fish would get sick.
 
Let me try to understand. Your main tank is now empty, right? Everything dead?

Either leave it fallow for two weeks without thermostat and then do a major water change or empty it, bleach it, clean all the media and start again.

You acn also, withou fihs, throw in potassium permangananet and leave it for a couple of days.

Water will turn res, whilie it is oxydizing everytning, the good and the bad, and then start again fom scratch.
 
I never saw slime loss with schock...it looks more like a very severe ph crash.

Without a pix nothing i can sya will help...

Your first description looked to me like maybe Costia....so, you see how without pix it is difficult
 
Main tank is now empty, everything died but the cat who is in another tank. He can stay there for a while if you don’t think it would hurt anything. Nothing was wrong with his fins or coat so hopefully it will be fine. So your saying I will need to leave this new tank full w/ no fish or heat for a couple weeks and everything should be ok and whatever was in the water will just die off? Would adding bleach help kill off whatever is in it or would this just be overkill? Sorry for all the questions it is just that nothing like this has ever happened to me, I really appreciate your patience. I also have the patience to just leave fallow if this will help ensure survival of future inhabitants. I just want to do what would be best to ensure no future fish get sick.
 
Imho, the surest way to go, would be to throw in a heavy load of potassium permanganate.

Watr will be red or a couple of days. As long as thereis any organic matter in the tank water will be red.

It kills everything..good and bad.

Then, it is as if making a new tank, staring from scratch.

At least you have that...

But wait for other, better opinions.

No worries, Man, we all learn with each other.
 
I wish I had of looked at the water sample at the lfs but he said pretty much everything was ok and I was only thinking nitrate, nitrite, and ammonia. He said the water was a bit hard but that is usually the case in the area. Now that I think of it with a clearer head the aro stopped eating about a week ago just after a water change. I have a rather large chunk of driftwood in my tank which keeps the ph in the low 7’s which they usually comment on as being low however I explain the driftwood and that explains everything. To my understanding water hardness and softness is due to ph so I can only assume something was wrong with the water when I did my change that caused some sort of problem. I just used my api test kit and it is getting a reading of over 7.6 which is about the same as it is coming out of the tap. Now typically the day after a change it is 7.2 so we’ll see where we lie tomorrow. I called a trusted lfs and he told me it was most likely also a ph crash. Now I just have to do a bit of research to see how this could have happened and ensure it doesn’t again. You live and learn but at least this time it was with juvenile fish instead of more mature hard to replace ones. Still bummed.
