I noticed what I thought were scratches on the frog, wasn't sure what it was, so I treated the tank with maroxy for a couple of days. The scratches went away. A week or so later, he started looking bloated, so I did a 3 day maroxy treatment. The frog's eyes are clear, he is full of life, and has a healthy appetite, but he is definitely bloated, and getting bigger. I have done frequent water changes as well. Is there anything I can do to save him? He seems happy, which is odd.
