Welcome!
Amen to Kurt's comments! Mixing species is rarely a good idea - while I won't say never, it's something best left to the very experienced. I also personally believe that 60 or 90 days quarantine is preferable - it can take a while for certain health issues to become apparent. I also believe (and not everyone may agree) that profilactic Chytrid treatment is a must before a new frog/toad (especially wild) is introduced - without treatment, it is simply too easy to contaminate frogs in other cages. Ask if you need help with this. Finally, I really really highly recommend finding a knowledgeable vet in your area and taking the toad to see him/her. If nothing else, the vet would be able to humanely euthanize the toad if it is needlessly suffering. Hopefully, it won't come to that!
Very best of luck, and please post any questions that come up!
