Frank, as a very occasional BHB diver (most recently two weeks ago), I appreciate your knowledge and insight about this.
It seems Moody Gardens is getting hammered on their Facebook site comments, with little response from the aquarium aside from a tone-deaf vanilla non-response about their breeding program. What might help is MG telling us who the collectors were, and what action MG took, or will take, against them. Are collectors licensed by anyone?
Plus what if any remediation is possible, or planned, or under consideration.
The biology of all this I know nothing about. Hell, I have a hard enough time determining when high tide is, and not leaving any equipment behind at the beach or shower area. But I do understand why everyone is so torqued off.
