Pairing a wheeler's shrimp goby Amblyeleotris wheeleri

[Common Blevil]

I have a big specimen (8cm/3") of this species of goby paired with a shrimp and maybe in the future will move into a larger tank( from 15 to 35 gallon). Will i be able to put smaller wheeler's goby in the new tank so it will pair up with my current one? Do they change sex like yellow watchmen? My fellow hobbyist says that they do, but I can't find any information in the internet.
I am always doing a lot of caves and crevises + my sand is so rich that my goby was surviving solely off it for 2 months after i got it and was fat when started peeking from it's burrow, so smaller goby will have a place to hide and things to eat, especially in 35 gallon long. But, like, did somebody pair these gobies/other amblyeleotris gobies (randalls goby, orange spot goby, aurora goby)? I'm not asking about people buying a mated pair, of course paired fish will not have any problems.

That striped goby is beautiful!

What are the plants you have in the sand?

What are the plants you have in the sand?

Caulerpa taxifolia, supposed pest that is "easy to grow" but in my tank it is really finicky for the reasons "too much corals" and "not enough nutrients". To stop it from dying i dosed nutrients, but it didn't grow much. Adding chaeto certainly didn't help, but i don't care. I hope that dosing + overfeeding will help. Caring for macroalgae sure is backwards to some aspects of acropora keeping, which is promoted everywhere now, so i did some pretty dumb mistakes, like not feeding enough.

On the other hand, halimeda grows steadily. The only algae i had that spread a little and grew from 0. Won't mind it taking over.

Caulerpa lentilifera on the other hand... Is not the algae that is spread a little, it is spreading a lot, a real pest. But easy to remove and surprisingly tasty!

You will have to find a smaller one, and introduce it preferably with some distance from your existing Goby. I recall they do change sex and readily form bonded pairs. Good luck.

Thank you, i will probably try once i wil upgrade).
Also if my scape will be +- the same(mainly the position of the shrimp rock, because i moved it 3 times and shrimp never left it the other goby will have a lot of place to hide.

As you can see, goby has his own corner(right side), which is good, because
1. I can see him from my bed
2. Nobody bothers him.
So i may keep it up in the new tank and the new goby will have like 80% of the tank to feel safe
