I have a 20g long reef mostly softies and LPS and 2 SPS Corals. I have a baby clown a firefish goby and a dragon face pipefish. I'm looking to get a sixline wrasse today because I've noticed some pests like flatworms and zoa eating spiders and I want the wrasse to clean em up. Im just wondering if he will get along with my other fish I've heard some people say wrasse is aggressive. lmk what you guys think and if you have any other fish suggestions if you think a wrasse isn't a good choice.
