Please any advise will do.....Peace N ThanxHow can I figure out if I have an American toad or if he's some other kind? Help.... Please?
This is what an american toad looks like:


They are found in a number of colors, ranging from light tan, to rusty red-brown, to dark olive-green. Some have little in the way of a pattern and are a solid color, while others may have a more variegated appearance with stripes or reticulation on their sides or legs and multiple colors on their body. Their ventral side is almost always a uniform tan, crème, or light brown with occasional dark spots or blotches. The back and body of American toads, along with most other Bufo species, is covered in bumps or “warts”. The two large bumps directly behind the toad’s head are called parotid glands and are used to secrete a poison when the toad feels threatened. There are two subspecies of American toad, both of which are identical except for their adult size. The dwarf subspecies rarely grows over 2 inches (5 cm) and is found in the southern most part of their range, while the northern subspecies generally matures to between 2 and 4 inches (5-10 cm) and has a larger range.


This is the type of substrate they need to burrow in:


Coconut husk fiber (bed-a-beast, eco earth, forest bed, etc.) is an excellent substrate, as are other safe soils. Avoid using soils that contain perlite or vermiculite. Peat moss, leaf litter, cypress mulch, or a combination of those can also be used. Simple substrates such as moist paper towels or foam rubber can also be used for temporary housing and work very well provided that they are changed often. Avoid using gravel, sand, or small bark chippings because these substrates are difficult for toads to pass if they are swallowed.


If you want to put a live plant, it will need to be a potted one.How can I figure out if I have an American toad or if he's some other kind? Help.... Please?
if you're really have to think about the frog like you are,i would suggest really doing some research first,like first buying a book,because you might be in over your head;even though you have the best intentions.don't take this question as saying anything about you,that's my last intention,i personally found that amphibians are a little harder to take care of than reptiles.i have a whites tree frog,and they are more of a prisoner of their environment than reptiles,or any other pet,except fish.so really do some bookwork first.good luck,i hope all goes well.
