I have an ACF that is 10 years old. Until recently it was very healthy and was kept in a 10 gallon tank with a couple of other ACFs. All of a sudden it has lost a ton of weight and isn't eating anything. It has a small lump on its side under the arm but that has been there for a while, even before it got sick. It isn't a weird color and has remained small in size. My frog's eye looks a bit dilated compared to a normal frog's eye. Can anyone describe what sickness my frog has and how to cure it. I've been changing the water daily in case it's a bacterial infection but I haven't seen much improvement.
