Adding second orchid dottyback

[Bars]

So 2 questions:
1) Do dottybacks change sex like clownfish/wrasses/... do?
2) If they do change sex, would I be able to add another to my established orchid?

I'm 99% sure his/her partner died, as I haven't seen it in over 2 weeks. I'd still really like a pair of them though. My tank's about 40'' in length, and 2' wide. Lots of live rock and seeing the remaining dottyback use absolutely tiny holes in the rockwork, I probably have a million hiding places for them.

Dottybacks are protogynous hermaphrodites, so they do change sex (born as females and larger changes to a male).
As for the second question I am afraid I cant help you.

The first question has been answered, the second question has an undecided answer. It’s almost impossible to answer with yes or no because of how hard it is to know how a fish will react with the same species in the tank.
Size of tank may be in your favour though, you can try it and see (Even if the other one is in the tank still I’m pretty sure they’ll form a harem). As long as the newer one is smaller than the current one(s) you should be alright.

Thanks, makes me a bit hopeful at least. I'm guessing if I were to add another one, my best bet would be getting a smaller one?

Ah that answers my above question. Guess I'll add another one soon. My established dottyback is still fairly small and doesn't seem overly territorial. Of course that can change with a new neighbor. We'll see.
