Anyone have experiences with them? Concerned with purchasing one online if I can find one, as my once pod infested tank has turned to a flatworm infested tank...looking at Sprung's "Invertebrates" guide gave me the idea to aquire one, as their life span is not very long, they feed on flatworms, are attractive to look at, so on... Anyone have any experiences? Early on in the tank's life I identified one of this type of nudibranch which hitchhiked in on the rock, yet have seen no rise in their numbers. As I had hoped their population would grow and feed on the growing numbers of flatworms, I am now looking to get this particular species. Anyone know where to find them? My tank is small, so I don't have many options for eradication of flatworms, and I will use no chemicals to remove them. Thanks.....Joey
