A question about gobies

[salt newbie01]

As my name denotes I am new to this hobby. Tank has been up and running for several months. I currently have 50 lbs LR, a few softies and LPS corals. I have a lawnmower blennie, rainford goby and 2 small false perc ( 1 1/4 inches ). I would like to add another couple small fish and eventually a mandarian once I get a lot more rock. I want to keep the fish relatively small so there will be less bio-load.
Enough history... My LFS has a bar goby ( long and white with verticle bars) would he be a good addition to my tank with what I am looking for. I had also thought about maybe a firefish. I want somethings that will swim in the open. The blennie hugs the rock and substrate and so does the rainford.

Thanks

Firefish will add some nice color to your tank, especially if you go with the purple variety. But make sure you keep more passive fish with them as they are very skittish. I see no reason why you couldn't keep a bar goby.

FYI, firefish are also very jumpy. I know some people who have been able to keep them without a lid, but most have to put lids on as their firefish jump out. Probably not a good idea if you don't have a lid.

I think the thing is they need to be with less aggressive fish. With peaceful fish their stress level will be down. Therefore, no need to jump. I have a purple in my 20 gallon with a yellow clown goby and clarki clown. The goby doesn't bother anything and the clown is too busy with his anenome
