I have a 29g fish only with 10 lbs of live rock tank. My tank is about 11 months old. I currently have 1 fire shrimp, 1 chromis, 2 ocellaris clownfish, 1 green clown goby, and 1 firefish. I would really love to add one more fish and fell in love with the Midas Blenny. However, I read online that the Midas Blenny might be aggressive. Do you think I can add the Midas Blenny without having any issues?
