I am a newbie to SW (55g tank is 2 months old)and the guy at a lfs sold me a sea apple, telling me, "Yeah, you can do that!" I was mortified to get home & start reading up on them - expert care only, "Death in a colorful package," - can kill your whole tank if stressed. I called the guy back & he poo-pooed the info I had read (needless to say, he didn't offer to buy it back!). I've had it about three weeks - seems okay, opens up at least once/day to feed. What I need to know is how to feed it properly. I recently had an ich outbreak, so have moved all fish to a QT. How much & how often should I add phytoplankton to the tank? Help! :squigglemouth:
