I really, Really want a decorator crab! I stopped my my LFS a little while ago and I saw their small sponge decorator crab in their 200 gallon tank. I was fascinated by it and I wanted to know what decorator crab if any would do the best in a 15 gallon innovative marine cube tank? I attached a picture below of the tank and it’s aquascape to see if that would help with choosing a crab! Currently the stocking is a pair of clowns a trocus snail and in the future I am planning to make this a mixed reef.
