Ill Leopard frog; PLEASE help!

[Lovino]

The first image is the single white spot left, second is the single dark spot left, and the last is the wound. Yesterday, it looked like the wound had scabbed over, but today the scab was gone, and looks like it got worse. I put him in a holding tank (which unfortunately is a plastic storage box with drilled venting holes) with saline solution in one side for him to get into. I use saline to keep off infection. I store it on a slight slant, so one side is wet and other dry.

Please help me with him! Im new to frogs, as you can tell from the pictures, im only use to them in a laboratory setting.

Please tell me a better quarantine set up, and how to mix the saline solution. I have been mixing very weak saline solution, 1 tsp kosher salt* per 2 cups water. And anything else I need, like how to care for the hand wound.

I dont have money for a vet either....


I will add he is still VERY VERY active, he hops away from me, and I think thats how I think his palm got worse

*i also have aquarium salt
