I've been trying to get them eating metro soaked food but they arnt eating anything at all the past couple days. When they were eating I was only able to get them to eat flakes.I know that Uronema is very common in Anthias right now so Metro is the best treatment I am aware of. If you aren't doing it already I would also be using Metro soaked food. Uronema can be internal and external with food dosing being more helpful for the internal version.
What type of copper are you using, and how are you monitoring it?
I'm using coppersafe with a Hanna checker
