Okay I don't know what I'm treating here, but I want to start with basic treatment without resorting to meds.
I moved my dp's into a 10 gallon tank that has been running for about a month. It has shrimp and plants in it that are doing okay, but that's it. Somehow during the move, one of my fish ended up with white spots on top of its head. Not ich, not salt looking things. Like, spots. Some big, some small. Like, four or five of them. It may have been the one I thought I squished with the net so it may be a surface injury. And no big behavioral changes, aside from the usual trying to swim right through the glass (just looking, not flashing or anything).
Anyway, when I moved them to their new tank, I placed them into my water change bucket (the one that catches the dirty tank water) with discard water from their old tank (and didn't sterilize the bucket first). I'm worried he transmitted a fungal or bacterial disease or something from that. I did a 50% water change in the new tank just before adding the fish. Water params are fine, no amm or nitrite, and trace nitrate.
I did notice the tank water was at about 83 degrees. My puffers are used to about 80. So I lowered the temp.
Hopefully I answered the appropriate questions.
I just want to add some salt and see what happens. Or give a salt bath? How much salt should I use?
