Hello all!

I have been looking online at petsmart and other stores, but wanted to ask those with experience about the cocconut shell substrates. There are several different brands sold. I an researching corn snakes before I buy one and was concerned about the danger of impaction and if cocconut has any adverse affects on corns, since it is obviously not a plant native to the corn's region. I am looking for a non-hazardous, attractive substrate to decorate a terranium. I don't want to live in an ugly boring place so why should my snake? Any other recommendations would be great. Thanks!
