Being a pretty conscientious environmentalist & former marine enthusiast (I had given the hobby up for years because of concern over the overexploitation of reefs) I recently started thinking about setting up an aquarium again, but to assuage my sense of environmental guilt, I was going to post a want ad on this forum for used aquarium equipment (e.g. used Maxi-jet powerhead, old-fashioned air pump, tubing) & stock a smallish aquarium with tank-raised or 'rescued' animals (e.g. bubble-tip anemones & spinecheek clowns...animals that don't require a lot of room) but then I wondered if I'm just kidding myself. Even though I was also going to do other greenish things like using Puget Sound seawater, lighting the tank with a compact fluorescent light only during the dark months & using natural sunlight the rest of the time, even put up extra solar panels to offset the electricity use, I still wonder whether the best thing to do, if I'm to stay true to my green philosophy, is to forgo the whole thing. Thoughts?
