Cardinal In Qt Help!

I just got 4 cardinals two days ago. I properly acclimated them into my fully cycled 10 gallon QT. This morning they were all swimming and schooling just fine. I came home to find one of the poor cardinals swimming vertically nose down. I also noticed that it almost looks like the scales near his tail are gone or lost all color. His tail also looks ripped. I immediately seperated him into my specimen container. Anyone have any idea what could be wrong? They all had red gills when I got them. They were all shipped to the store the same day I picked them up.

Tank was processing 1ppm ammonia before fish were added. I have a presponge filter over the filter intake.
Only meds currently in the tank is a dose of prazipro.

Hopefully the photos all load and don't do that bug again.











I'm spacing on who to tag atm.

Poor little guy. Is your ammonia still 0? It could be that getting shipped to the store, dunked in their tank, and then moved to yours was just too much for him

He was swimming straight for a bit but now he's back to vertical.

The manager at the fish store (who actually know what they're talking about) said it might be bacterial. Any idea? I have a handful of meds but I'm unsure if I'd need to treat the entire tank or just him or what med to use or if any of them would work.

I have:
Furan-2
API fungus cure
Tetra life guard
Paraguard
Maracyn two

 

Bumping this for you.
And a wild guess would be that this is acute septicemia. Kanaplex would be a good place to start if so. Part of me doubts osmotic shock but without more water parameters it's hard to say.

 

I just tested water parameters again. Ammonia and Nitrite are both still 0

 

My guess is it's just stress from moving tanks twice in one day. The best thing you can do is leave the little guy alone in the dark for a while.

The light is currently off. Should I keep them in the specimen container or should I put them back into the tank? I can add a small bubbler to the container.

 

I thought only one was acting like this? I'd keep him in the container, floating in the tank if necessary. Holes for water flow.

There is only the one that's like this. the container is a thick plastic with no holes. I'll add an airstone

 

Unfortunately he did not make it through the night.

Thank you for the help junebug

 

I'm sorry hun.

I would spend a little more time on looking at the suggestions made by Raimy101 as both of them could imply that other fish could be effected. I would start off with osmotic shock which basically means that the parameters of the water (not the quality as in Ammonia/Nitrite/Nitrate) but the GH KH and pH values. If there is a sudden change in these water conditions, the effect on the fish can be devastating and by the looks of your dead neon, it looked healthy .... so something effected it. Changes is water parameters knock the fish into osmotic shock.

I did acclimate by floating the container for 20m then slowly adding tank water into the bad for 2 hours. Filled it up then dumped half of the water then filled it again. Then I netted the fish. Wouldn't that be more than enough to prevent shock?
One of the cardinals were harder to catch. Possibly it was this one?
