I have only kept Orbiculate's so i can't comment on the others, but I wouldn't recommend one in a 180. They get big fast. Mine went from 2 in, to 14 in less than a year. He's huge, eats a ton! I have mine in a 400 that is 36in tall and I think he could use a bigger tank. I also have a lot of tangs and a puffer and have not had any issues with his fins getting nipped at. HTH.
