Watchman vs. Clownfish

[sstanle4]

My watchman goby is attacking my clownfish. They've been in the same tank together for about 3 weeks in my 14 gallon biocube with no problems. But the past few days, the watchman is sneaking up behind/under my clown and nipping at him. The clown will twitch like crazy and then swim away. Will this stop by itself? Or will they fight to the death? Advice?

Well that isnt enough room for those 2 fish. The watchman is prob doing what hes doing because the clown is too close to the watchmans home.
