No, I have never even heard of this place. But I can almost guarantee you that they don't have 100 species of puffers. There are only 120 species worldwide, many of which are extremely rare or live in the deep sea. I would love the source that you used for your statement, they must have some rare ones at least
Edit: I looked it up for over an hour, I'm deeply impressed. I wish we would have gone here. They don't have 100 puffers, but perhaps they reach this total when counting all Tetraodontiformes they had over the last few years.
