The Darth Mauls are really expensive I only know 2 places that sells them online and they charge $50 per polyp. Mine just popped out another baby this week. I started out with 3 and then 2 died and i was down to one but now i'm back up to 3 again. So 4 months i'm back where i started. But the one i have is real healthy now. When i first got them the other 2 polyps were little and they just withered away. But now the polyps are huge and always open even at night when the lights are out.
