Hi all, I recently bought an Albino Pacman frog last Saturday. He's I'm guessing about a month or so old. In a week he's seemed to double in size, but that's not the reason why I post. Yesterday when I got home from work I noticed my frog acting strange. He kept rubbing himself with his feet, and sucking in his gut, on each side. He also kept opening his mouth, looking like he was trying to puke of something. It looked like his skin was irritated, or something wa hurting inside him. He did this for about an hour, until I decided to push him into his water dish, thinking that maybe something on him was irritating him. After being in his dish for a bit he stopped acting weird about 10 minutes later. Then today I noticed that his skin was looking dry, and that his "white" areas were turning green. The green really doesn't look right, and the majority of the green is on both sides of his gut. Also in the last 2-3 days he doesn't seem to have eaten any of his crickets. Can anyone help me out as to what might/might not be wrong with my frog, and why he was spazzing out?
My setup for my frog is a 20 gallon tank with Naturebed for the bedding. It's that brick of bedding that you put in a bucket and water dish and it expands 7/8 times bigger. I also have a water dish and a fake plant kinda overhanging it. Humidity and temp are between 70-80. I use dechlorinator drops for my mister and water dish. My lighting is a UV-B Flourescent light, that I leave on for about 10 hours each day. I feed him pinhead crickets, which I feed with Gut Load.
The picture(if it works) is of my frog from 2 days ago. Notice the green showing on his stomach and back, which wasn't as showing as it is now.
