I keep a variety of frogs, including two pacman frogs. Both are Ceratophyrys cranwelli. One is normal green, the other is albino. I got them as small neonates, and now they are getting bigger. They are easy to care for... super fun to watch eat. Unless you live in the south of the US, they will likely need supplemental heat. I tried my two newest without it and their appetite decreased, as did waste production. Now with heat, they are eating like hogs again.
I feed crickets, dusted with calcium supplements, 3-4 times a week. Once they reach a decent size, you can offer them a pinky mouse as an occaisional treat, but a steady diet of pinks can cause corneal lipidosis, an accumulation of fat behind the cornea on the eye, which may eventually lead to blindness.
Housing is easy- any container works, as they are not especially active. I have my smallest in a divided reptile ranch style critter keeper, and the largest in a 10 gallon. A 10 gallon, or a 20 gallon is the largest they will EVER need, and only the largest of large will ever need the 20. They cannot climb, but crickets can, so a screen is a good idea.
I have a lot of info about them on my website. Feel free to browse it if you want, and if you have any questions, I will check back, or PM me.

Good luck!
