Hi, just wondering what the people who have a royal or bicolour dottyback, have in with this grumpy little fish? i think he's awsome but compatability is difficult, he doesn't harrass the clowns i have but he was put in after them, but just wondering what others experience is. I would love to put coral gobies or a bicolour blenny but he might be too mean for them.It's a 170ltr/45g? tank. any suggestions? Thanks!
