I am a fairly new reef tank owner. I have become amazed with zoos and have just added quite a few(about 50-75). I found your forum and began reading about how nudibranchs are not good and eat the zoos. I have 1 Lettuce Nudibranch which many say is considered a sea slug. Do i still need to remove this Lettuce Nudibranch or will it be fine with my zoos. Please help quickly so I can get some sleep tonight without worrying about my poor zoos.
