Reason for selling:

"Well... ironically now that I finally am able to culture pods efficiently my second female unexpectedly passed away.
No signs of illness. Just recently I got grass shrimp from the coast and she was very agile and very interested in hunting her food.
So her passing was as unexpected as Poppy's earlier this year.
That leaves me with the male who seems happy and healthy and I am at this point not thinking of getting any more females.
My breeding efforts are coming to an end with this. But I'll still enjoy my seahorse boy in the cube by himself..."

The set up above is used by places like Seahorse Source to successfully raise pelagic fry. It really is a great set up.
