It’s going to be hard cause you have to know a LFS that trusts you… ALOT. Introducing coral into a system safely takes along process if they care. If they don’t, buying from wholesaler relatively cheap. Mariculture colonies are 20-50 and a couple of dollars per frag. You’re always going to make a bit more selling packs on reef2reef.
2 places I’d call an ask is Nemo and Atlanta Aquarium. It’s a really slow season and time for a lot of hobbies tho.
I’d just make like packs for 200+ and see if that’s sells. Lots of us getting out, very few are starting.
