I agree, for monsters that tank has a rather small footprint. It might work well for a reef tank though, but for 30 grand one could build a heck of a monster tank.
Living Color makes some good stuff, but I don't think that 30,000 is reasonable, especially with no filtration and shipping extra. It does say that the price is negotiable however.
I guess the idea is to keep in mind that they are a charity and that you could get a tax deduction possibly, which is why they are most likely asking at least initially such a high price.
