Clownfish Lymphocystis or something else?

I bought 2 clownfish about 1.5 weeks ago and have them in a qt tank. One fish seemed off from day one, not eating and staying in a corner. The other fish seemed fine and was eating regularly. Unfortunately I lost the first fish on day 7, fish two still eating fine. Now the surviving fish has a bump under its lips and is starting to seem a little less active. Is it lymphocystis or something worse?

I have dosed the tank with general cure and mixed up medicated food which I fed for the first time today. I have cupramine on hand as well which I started to use in the beginning but discontinued use when the first fish wasn’t eating since I know copper can suppress appetite.

Parameters:
Temp: 77F
Salinity: 34 ppm
NH3: 0
NO2: 0
NO3: 5
I’ve been doing 25-40% water changes every 3 keep water quality up.

I’m still new and learning so can use whatever advice anyone has for me.

Just curious, did you get them from your LFS or from online?

LFS.

It’s so frustrating how they look great at the LFS, then as soon as they get home… BANG. Trouble. I hope he pulls through for you.
