What is a good beginner coral to start with THAT IS NOT A PEST CORAL! I really dont want to deal with gsp or Xenia overgrowing or something similar. Just a simple soft coral to get used to corals. This will be my first coral btw and this is my first saltwater tank as well. Would toadstool leathers be good? I just want something that I won’t regret or something that isn’t a pest. Thanks!
