I think I will use the 55 for fish. I was reading that both corns and balls could go into a 20 gallon. If I made two 20 could I have both of these or two of the same type and possibly breed them? obviously I'm still a begginer but 20 seemed a little small for both so I would be willing to go to about 30 gallons. If not I can get the sand boa but I saw a nice python at the pet store by me for a reasonable price.
I dont have anything more to say.
