So what would you do? please help!!?

i have just traded a bunch of **** in on amazon.com and i have around $230 on amazon. i can get all teh supplies needed to convert my closet, (dimensions - 7' high, 4' long, 2-2.5' wide.). so do you think i should buy these supplies and make my schneiders skink a larger cage. or should i spend the money on a new fish tank for my snapping turtle? the schneiders can(keyword) stay in the 20 gallon long, but bigger is better. or should i move my snapper out of his 20 gallon long into a 50 gallon now, he is only around 3" so its not an emergency, but who do you think i should upgrade. i will be upgrading both, but which one seems better for now?
