Brandon429,
It really bothers me to see anyone say that your experimenting is in any way "wrong", as some of your systems have been created with an ethical concern for the animals care, as well as the advancement of the small system's boundaries. Do not worry about the concerns of naysayers in regards to your lovely microcosms, as I look forward to reading your frequent updates on these tiny systems. How cool is it that you have beautiful aquatic creatures in a vase, doing well, happy, and in fact growing to the point of regular fragmenting? That in itself is mindboggling, as the general mentality is "it cannot be done, it's cruelty, it's too unstable, it'll never work." It is readily apparent to myself and others, I'm sure, that you could maintain a larger system or two, given the extreme amount of attention to detail you give these smaller ones, but you choose not to. Instead, you go above and beyond, and for that, you should be applauded. Keep up the good work! Joey
