Advice on mixing dragonets?

[Bloodasp]

I have a resident madarin in mine, bought another one thinking it was a female (it was hiding it's pointed dorsal fin when i was watching it in store). The resident chased him till it jumped into the overflow where I left it until I was able to return it to the store the next day.

Thanks for the educated responses! Looks like I'll have to find a different home for him.

And yes all three eat frozen.
