Problem with Albino Pacman Frog

[Casualties138]

Daylight bulbs will burn an Albino's skin and can cause them to go blind. If necessary just move the frogs enclosure so that a little mire daylight shines in, but DO NOT place the enclosure actually near the window. so that there is no actual greenhouse effect within the enclosure. Use a UTH placed on the side of the enclosure for supplemental heat like Namio has suggested.

He is also right about any live plants. Nearly all are toxic to Amphibian especially if eaten or the juices from the ant get on their extremely sensitive skin. This can irritate the skin causing stress. Ingestion can be fatal or cause irritation of the digestive tract.

What kind of water are you using for the frog's water dish. You say de-chlorinating, but many people confuse de-chlorinated with distilled which although it contains no chlorine it also contains absolutely nothing. Distilled water is fine for misting and fog machines, but is harmful to the frog if used as a main water source. This also goes for expanding the frog's substrate. Distilled water contains no mineral/salt content that assists the frog in hydration and regular body and organ functions. It literally leaches the vitamins, minerals, and salts out of the frog slowing killing it. This will also cause severe stress.

De-chlorinated water is tap water treated with a de-chlorinating agent/water conditioner. The same stuff for fish tanks that removes chlorine, heavy metals, and Chlorimines. Your other option is All Natural Spring Water which still has the mineral/salt content, but contains no chemicals.

Are you using the correct water??

i dont know how else to make it clear, It is not the plants!, i KNOW that toxic to us is different than toxic to amphibians, I know what i am doing in that department. So that is off the table.
As for the water, I have used distilled in the past, but usually just use tap water with the dechlorinating drops you can get at the pet store...I have also heard that if you leave regular tap water sitting out for a couple days it does the same thing as the drops, just out of curiosity..is that true??
I think the problem was the light, I turned it off today and when i came home from work he was not on his back like he has been the last few days. This seems strange though because like i said I have had him for a couple years (and had that light as well) and nothing ever happened until now.
Also, Since i have a heat lamp (red light) should I also add a UTH..and if so, Ive been told not to put an UTH on the bottom of the tank...is this not correct?
