I have tried growing this zoa in the past, I ordered from a hobbyist in Cali but it came in small and never really open up. That was $400 down the drain but the other stuff I got from her grows amazing. I believe between it was small and the plane trip from Cali to Florida really stress it out and so I decided if I ever buy stratosphere again, it will have to be local so it won’t have to endure the stress of shipping. This year in RAP Orlando, I was only looking for 2 things, CSB and stratosphere, there was 2 CSB at show but they dealer wanted insane prices of $1500 and $2000 for relatively small one; and stratosphere was nowhere to be found. Talked to Rudy of GB coral and he told me a lot of them have melted and he have people asking him to find them for $500pp. I was help a friend point me toward someone that had a frag in Sarasota. The owner work along side an online vendor and they invested money on 1 polyp but over 1 year they have double it to grand total of 2 polyp. But according to the owner, it have been happy and stable, and it would only be an hour drive , so I went for it and got the 2 polyps for a decent price.
