Adding another goby?

I'm looking at purchasing a 2nd diamond goby, as I just upgraded to a 90 gallon tank. I've had the original for a few months now, but with the larger floor area I thought a 2nd would be nice.
Now my only question is what is the likelyhood they will fight? I plan to purchase this on my trip to PA on the 1st of July, so I have time.

It's my understanding that multiple gobies will fight, but get a second opinion.

I alsi think they might fight. A different goby maybe?

I've heard mixed stories on diamond gobies. A lot of people say they can live together, but I wasn't sure. I already have a firefish goby as well, but he's kinda boring.

firefish arent really gobies (they are dartfish)so thats why there isnt any aggression really happing. multiple gobies will usually fight but sometimes u can develop a pair by some luck. if u get a smaller more "timid" one u may have luck. also due to the size of your tank u should be ok...if u go with a different typr make sure it doesnt resemble the diamond goby to much, this will lower aggression a lot.

Thanks . I want another Diamond, as I love watching him..but he finally started to venture to the other side of the tank, so if he can keep it clean, I'll stick with one, else I guess I can make an attempt. He isn't too big yet, 2-3" long. I saw a giant one at the store, he was like an 1" in diameter. Crazy big.

when they are young u have a pretty good chance still at that size u may have some luck introducing another.
