I am doing a mini reef system 12G aquapod and I was wondering when it comes to false Perculas wether they would be ok singly or should I have at least a pair? I currently have 1 bicolor blenny, 1 sally light foot, 4 blue leg hermits, 1 small button polyp colony, a small mushroom and yellow polyp and a small zoa colony. I was thinking of addin a plate coral, hammer or frogspawn for the clown/s. I just am not sure if a clown by itself will be happy or if it will be happier with a friend? I also would like to add a small goby later on...any info / suggestions would be awesome thanks!
