One of my frogs, developed a red spot on her nose a week ago, but was otherwise eating, swimming and acting normal. Thought it was just a scratch at first since she has a habit of darting down super-fast, but it's not gotten much better. It’s less red now and all white than when it first appeared, and somewhat the same size, but she can only take little bites here and there and started keeping to herself sleeping during the last couple of days so I am worried.

My first time having frogs so no expert, but I think this is Mycobacterium? There is no signs of anything fungal though, which I read is also a symptom, but maybe not always? She also had a successful shed this morning, though she seemed to not want to eat it since it was still floating in the tank.

She is currently isolated from the rest of the frogs.

Is this Myco, or something else? And whats my next step for helping her get better? Any thoughts would be greatly appreciated.

On a side note:
I do have another frog with a red dot on the hand. She is still swimming, eating and being very active. I will post her little injury next for thoughts and advice.

Thank you
