Clownfish pair.. can larger fish become male?

[GOSKN5]

So I have had a black snowflake occy for about 4 months or so, recently I added a small occy in hopes of a pair forming. The two have been gotten along great since the start..

Recently it seems the smaller, new addition occy is the dominate one and the larger one usually does all the "SHAKING" and seems to be submitting to the smaller one...

There is a significant size difference as well... the small one is about an inch and half maybe.. the larger a good 2 3/4 or more...

I assumed the larger being alone for 4 months or so had become female and the small one would become male.. maybe they both were still juveniles and working it out? Can the female do all the shaking hahaha??

I suppose it's possible as size doesn't necessarily mean dominance

I got a Snowflake-Onyx pair. The snowflake was initially larger by 1/2 inches but as the mature the Black Onyx become dominate and get larger and become the female of the pair.

Well, I got an (awesomely beautiful) 3" wild caught Polymnus, just this month actually.

I bought it, after noticing that the fish had been in the store for two years with something, clearly, stuck in it's one gill. I removed it with one of those v-shaped nail-knifes and it is doing perfectly fine now.

But, as all this stressed the fish, I noticed that it twitched from time to time in the first few days, despite myself being the only living thing in sight.

I've added a tame ocellaris half it's lenght (but more like a third of its size) and it fish-friended the Polymnus at first sight. The Polymnus is very protective of the little one, and also dominant of it as well, but it might be too early to tell if it remains that way.

If the twitch is only a male trait, mine must be an older male I guess.

My ocellaris clearly dosn't fear anything, but the wild one acts completely differently and much more carefully. But besides that, all I know is that I love them
