Just wanted to post about this new marketplace a friend is working on that just launched. It’s called Aquarium Hub, and it’s kind of like ebay and/or amazon for fish, corals and equipment. They provide overnight shipping for only $20, which is insanely cheap. As a vendor, I believe it charges 8% fees on sales (they use stripe) but it seems they’re really trying to protect buyers and sellers on here (can’t remember exact details).
