Hi everybody, I have a 60 gallon shallow rimless reef lit by two radions, a tunze skimmer and refugium for filtration, and flow provided by a jebao wp40 and jebao rw-4. I have a few lps corals and a monti cap thats doing great, and an ORA bird of paradise birdsnest thats doing great. My question is, whats a good starter SPS thats a little more challenging such as an acro (I really like ORA red planet acro but not sure if im ready yet)? And also, what's your favorite sps coral to keep, and why is it your favorite? (trying to get ideas for the future) Thanks for your input and any advice you may have!
