Depends what you want. I have alot of polyps and Dendros, and if I feed my fish near to when the lights go out, polyps come out fast to eat the scraps from my puffer.
But I like the motion of GSP, Jasmine and Clove polyps. When you have to many, just reach in, tear some off, sell scraps for $5 a peice and you get some spare cash. Its easy to trim and keep clean, grows fast, have neat coloration.
A added bonus, if there is a lady in the house who thinks the tank has alot of ugly inhabitants, they look like little flowers! haha
