16 gallon stocking help

[Fishsticks2187]

I have a 16 gallon tank with a pinked streaked wrasse. The pink streaked wrasse is extremely docile and shy. At first by hiding out for the first day, but now he's goes everywhere In and out of the rock work. He's been in the for 2 weeks and is doing we'll. I was looking to get a clown fish and a possum wrasse as we'll. the possum wrasse is ver similar to the pink streaked wrasse, but my LFS doesn't have any In stock. But they did get in what they are calling "nano" clownfish. Now I know there's no suckh thing as a "nano" clownfish, they are really small (probably about 1 inch). I was wondering if I get a clownfish and then get the possum wrasse later on in a few weeks will the clown mess with it since it's new to the tank? Or will it's not bother it since they will be about the same size. I know clowns sometimes have a reputation for being bully's when it comes to there territory so I'm not sure if I should just wait and add the clown last.

Sorry for the long post lol

nano probably just means the clown is small. occellaris clownfish are docile ime
