I've really been getting into gardening over the past year and have just started looking at aquaponics. I hope to one day build my own homestead, and want a big greenhouse with a central aquaponics "pond" for raising fish and shellfish.

After looking at lots of setups online, I see it's possible to grow lobsters, clams, oysters, tilapia and many many other critters using aquaponics. But I haven't stumbled across any that combine different species in the same water.

Question: Is it possible to have all four of those in the same tank? Or would they need to be separated? Any special considerations here?

Probably going to build a practice setup in my current house, just to get used to everything. Which critter is easiest to start with? Maybe the tilapia?
