Goby Breeding Experts!

I was wondering, I have a Yellow Clown Goby and a Orange Firefish. I was interested in breeding them, But how do i know what sex they are?!? My Yellow Clown Goby has pink blush on his cheeks, does that make him a girl jk. But how would you tell? Is there a way to visibly check?

I can't help you at all with the clown gobies, and the firefish pair I had didn't show any obvious sexual dimorphism but once they paired up there was a little bit of behavioral difference.

My firefish pair, probable female closer. (based on it looking like the near fish is egg bound)

This picture was taken just a couple minutes later, the "female" is in the burrow peeking out, and the "male" is standing guard.

She is just barely visible in the lower right corner at the base of the rock.

The showed probable breeding behavior for a few months. They would both be out regularly, then one would disappear for a week or so, with the other spending a lot of time in the burrow too. Then suddenly they would both be out active again.

Hmm, well I wouldn't be able to see until they mate and the tummy is showing then? MY firefish hides like that but she doesn't have a partner. It only comes out when It hears me open the top to feed.
