I picked up a black saltwater Molly from my LFS today. I’m hoping it can help me identify if my fallow period was successful. I had velvet, went fallow for 45 days. I put it into my quarantine tank. My LFS had them already acclimated to salt and was tied to the same system as most of their other fish. It’s healthy looking but that’s what I’ve thought before about other fish. Can I use a copper treatment on it? (Copper power) and can I use prazi? I plan to hold him in quarantine for a minimum of 30 days. Any tips? Thanks in advance
