Sick puffer - Can’t seem to figure out what’s up

[Rocksor]

Yes that is total ammonia measurement.

On the molly, it looks as though the gill plates have been slowly eroding.
Would that be a sign of a bacterial infection? Is it related or a completely separate issue?

As of current, every other fish looks and acts completely normal.

 

[Deadeye]

Hasn’t gotten better or worse. Metro doesn’t seem to be making a huge difference.

The gills have started looking much better.
I’ve started treating with kanaplex as well to try and help.
Still no white stringy poo.

 

[Deadeye]

After a bit the red came back. Honestly I’m not sure if it’s related or something else.
Metro and kanaplex haven’t made a huge dent.
White stringy poo just reared it’s head (without any mysis meal before hand), so I guess I have better reason so suspect parasites. The first round of levamisole just went in.

 

[Deadeye]

Going to do the second levamisole dose today, if that doesn’t do it (and there hasn’t been a change - better or worse - with the molly) I’ll try prazi.
If that doesn’t work I may just try acclimating the molly to saltwater…
