Hey all! I feel like the PAC section has been a little dead lately!!! How's everyone doing!?!?

I have a question for you seasoned veterans.
Is it safe to use a rack system for pacman frogs? If so what size would you recommend? I just purchased a 3 bin sterilite plastic rack and I was going to house my frogs in there but then I wondered if it were possible to use regular racks, or do you guys recommend a different type of caging?

Also, I have one more that came to my head. And I will probably end up with another one by the time I'm done typing this one...
Is there a strong market out there for frogs and more specifically pacman frogs? I only ask this because I would prefer not to try to breed them if there is not a strong market. It's not only about the money at all, honestly if I could keep 10000s of frogs I would lol, but I would only breed them and sell them if I could make a little to keep my hobby going, such as making my collection self sufficient. I wouldn't want to endanger my frogs or put them through the stress of it if in the end it wasn't necessary. I hope I don't come off as a money hungry person, but I'm really not and don't care if I couldn't sell one, but if that's the case I would not want to subject my froggies to the extra stress. And this is to say if i would even attempt the complex art.

Thanks in advanced for your helps and I look forward to hearing from y'all.

Any PA frog keepers here? Would love to meet local enthusiasts such as myself!
