I just bought a pastel bp and haven't gotten a perfect measure on him yet but he is just over 3 ft I believe. He is five years old. I only have a 24x12x12 tank right now and I know it is way to small. What size would be the best for him? I want him to be able to reach his full length and have room to stretch out. About the best thing I have found so far at our local pet stores is a 30x12x12. I really do not want to buy this tank because I think he will still be a little crowded.
