Possible impaction

[Amphibious]

His stomach felt normal, but he felt like a bag full of water. Is that how a pacman is supposed to feel?

It is kind of hard to describe how they should feel... It's usually pretty easy to tell if they have a hard spot. Even after a big meal they can temporarily have a bulge on their side (not an impaction, just a really full belly!) Can we get a few details such as temp and humidity (these effect digestion), what his diet consists of, and how often you feed it?

Also, Pacmans tend to poop in their hole then relocate to a new spot, stay there until they poop again, repeat process. So even if you haven't spotted his little presents, they might be there. Does he change burrow spots often?

[Amphibious]

I figure he's all right. He felt soft but hell, he's a frog. There was definitely no hard spot on his belly. He changed his burrow once. He relocated to the side of the tank furthest away from my bed. He kept that burrow until I changed the tank at which point he dug a new one in the same place. I am having trouble keeping the tank humid enough. It's usually between 60-65%, and I have come home on warm days to see it too dry. The temperature generally stays between 70-80 degrees and never drops below 65. His diet has lately consisted of night crawlers. I have been feeding him nightly because he appeared to be underweight when I got him.

Baby pacmans need more warmth. The daytime temp should be around 80, even up to 85 is fine. It's better for the humidity to be above 70%. To keep the humidity in, you can partially cover part of the terrarium lid. This will help keep the temp and humidity up. You can use a damp towel or plastic wrap. Be sure you leave about 1/3 uncovered so that your Pac still gets airflow. If you use plastic wrap, poke a few holes in it and don't put it directly under the light.

For young pacs, you definitely want to offer food every night. It may not eat every single night, but you should give it the opportunity to. Your frog is going through some very important growth developments, so a steady but varied diet (and calcium dust!) is key to growing a strong, healthy frog.

You can also set a piece of glass or plexiglass on top. Just a warning: be cautious about using plastic wrap as it can release toxins when heated.

I don't know if he's a baby per se. He's the size of my palm, but I was told by his previous owner he's less than a year old. In any case I will conjure something up tonight to hold in heat and humidity.
Do you have a particular calcium supplement you recommend?
