I was curious about getting a boa but im not sure what kind i want. So if anyone could kinda tell me what would be appropriate for my tank so i can look further into that kind. now the tank i am currently working on and that i have posted about quite a bit is 3 tall 3 wide and 18 inches deep. abotu half of the bottom is a pond and there is a second level and then a third level that is more of a ledge about 18 inches by 18 inches. Now i cant go with a snake that is going to be too heavy because i dont want him too way down the ledges, that are 1 1/2 inch styrofoam. I know that they can take a good bit of weight (20-30lbs) as i have it now but a snake too fat will not be able to lay on the ledges well... Which makes me lean towards a rainbow boa as i know they are a pretty tame size, but i want something that will get a decent length too. the bottom level is only about half land as is the second level but i may end up making this second level bigger so it will have more area but they both have about 3 square feet. I'm sorry if im not describing the tank well but any suggestions for a snake would be much appreciated at least that way i can look further into them.
