I have a 4 spot pacman frog, a couple weeks ago I went to feed my pacman and he started breathing heavy, like his sides were going in and out fast and then he spit up water. I let him be for 2 days and he was fine, just today I went to feed him and the second I opened the cage he started spitting up breathing heavy and now he had the water coming out his nose, normally he is fully under the eco earth but the past 2 days he has been on the top just sitting and he looks darker green, his eco earth is always moist, i swish it around every other day, It is 45 for the humidity and 83 in his tank he is about the size of my palm so 4 inches long, please help!
