To clarify Gresham's point, there's a food chain when it comes to "pods", so to culture them requires some specificity when it comes to the intended outcome/goal.
For example, If I were interested in cultivating Tigger-Pods® (sorry Gresham my 'puter doesn't do the little tm), I'd of course want to feed them and give them ample space, no problem. However, if I were to be a little lackluster with my diligence and allow a single Mysis shrimp into the equation, it spells doom to a huge percentage of the "podpulation" (my word, thanks!). Mysis shrimp are like tiny mantis shrimp that club and destroy everything in their path, causing Tigger-Pod® reproductive energy to turn into survival/hunting energy for a much larger and more efficient predator.
