Ravennreef, I beg to differ, they are not ugly, they are cute, IMO. I guess we all have our own opinion, but if you take care of them right, they will not ink and crash your whole tank, as I stated before, I have never had one do that. They are great additions to a tank, they have lots of personality, they are social, so if you get one, I would get 2. If you do a search for seahare, i have made many posts about them, check them out. I forget who, but someone else on this board just got 6 for in their tank.
