The other day I noticed he had a small whitish spot on his lower body. It looked like he had maybe swum too fast past an ornament and scraped his scales. Today, it looks worse and puffy. I think it is a fungus.
What do you think is the best medication to treat fungus for an Oto?

Pictures (sorry for the quality--I only have my cell phone to take pictures):

I really can't tell from the pics but it looks like a fungus. Ottos are really sensitive little guys.. Do you have a QT tank. It doesn't need to be big a 5 gallon would work. I would make sure you do daily water changes and keep his water as clean as possible. Meds might be needed to take care of it. Hopefully someone can come along that's had to deal with it and give you some help.

It's probably a fungus. I'm going to QT him. What is the best treatment for a fungal infection for Oto's? I've never had this before.
