having these mesh containment/release areas with varieties of live foods is a great idea.. cichlids, livebeares, crustaceans, snails.. could work with them all..
also an FYI I found a snap-togethor climate controlled greenhouse for around $2k.. if I remember it was like 20'x8'.. came with auto-retracting 'moonroofs' that were connected to digital temp control.. could do heated coils in the cement foundation, and also design your pools into the foundation.. then once the greenhouse is in place, you can build much more from the ground up (racks of tanks on the central filtration system for housing newborn rays.. etc)
