Help! Sick Blue Spot Jawfish

[pamsreef]

I've had this BSJF for a month but yesterday she wasn't staying in her home and her color didn't look right. This morning her color has worsened so I set up the quarantine tank and I have her in there.

Her body is very grey and slightly white. I desparately need to know what I should treat her with.

Thanks,

Pam
