If the Goby and Blenny had issues with one another what would the reason be? Possibly because they are similar in size and or shape, competing for same real estate? If the watchman was left off what other fish will sift sand like the watchman goby would that wouldn’t have issues?The Starry Blenny might have some issues with the Watchman Goby, but it's hard to say for sure. Other than that the list looks very well balanced. Pretty much all of those fish aren't overly aggressive but they will stick up for themselves if the other fish get pushy, which is ideally what you want.
