No they both take completely different care. One lives on the beach, the other in the savannah. They don't exactly mix. Also, the hermit crab could hurt your ball python.
Your python may stay small but that is NOT good for a python to be in a small space. It leads to agression. You must get bigger tanks for your python as he grows, or just start with a large one.
Provided the tank is clean and has been set up correctly there should be no problems.
you have to make the food appear alive
A 30 gallon tank is alright for a blood python baby, for now. Once the blood python begins to grow it will out grow the tank.
A tank
i have a ball python of my own and it came from the pet store in.......i guess ,a 20 gallon tank and there were two other snakes in there with him . SO he, or she, should do fine : )
It depends mostly on the temperament of the Ball Python in question. Some Ball Pythons will share a tank with many other species of Python and Boa while others want to be alone. for example > I have a Nicaraguan Boa who shares a very large enclosure with 3 Ball Pythons and they get along well. In some emergencies when i have to leave and take all of my snakes with me all 15 of my various Pythons, Boas and Corn Snakes get along well enough to share the 8ft by 6ft travel container that I have.
You can keep a horseshoe crab in a saltwater tank, as long as you have a large sandy bottom. If the horseshoe crab becomes too large, or starts knocking things over in the tank, get release it back into the ocean or get a bigger tank.
I agree that a 20 gallon tank isn't big enough and they won't be very comportable in it but ball pythons don't get longer than 20 feet,the longest a female would get to would be 5 - 6 feet and a male would get to about 4 - 5 feet but that's rare! You could use a 30 gallon tank but the best would be a 40 gallon tank for a fully grown ball python!!
If you cleaned it

You should clean your hermit crab tank once a week to maintain a healthy environment for your pets.
