Tomini Tang + Goby = Possible?

[Moogled]

Do you guys think the Tomini will rain destruction on a Yellow Watchman Goby? He previously chased a rock blenny relentlessly and nearly killed him by starvation.

Will the same thing happen to a YWG? I know it's possible because the two fish are similar, but I'd like to hear some opinions and predictions. Some blennies leave each other if they're different color enough (or so I'm told) so I wonder if the yellow color will give the goby enough leeway to survive.
