I’ve had this guy a week in QT. He’s fat but I have not seen him eat. He’s very skittish and hides so when I feed, I go away, let him hopefully eat, then remove leftovers after about an hr. he’s gone through 1 dose of Prazi. On his 2nd dose now and 1/2 dose of copper was added yesterday. 2 days ago, noticed a few scales in the tank. Scooped them out. Today, LOTS more. Photo of toilet w scales removed from bottom of tank today. What’s going on. He appears to have a lesion. What can I do for him? I’ve got a ton of different meds on hand
