Goby plus Goby question

[mgirdwood]

Hi
Currently i am recreating my 90L nano tank after a few issues and would appreciate some thoughts on adding perhaps a new Goby, reason would be to help to keep the sand clean rather than CUC. However i have already a small Black Ray Goby paired with a ( i think) a tiger pistol shrimp. neither are that large at the moment although he is digging out his tunnels quite well. In addition i have a pair of Clowns and a small number of Trochus snails.
I guess the question is whether the 2 gobies and the pistol shrimp would be able to peacefully live around the sand bed together ?

thanks for any suggestions

Yes they would "probably". I have many gobies and they ignore each other. But I said probably because even if they are different species, some male fish will fight with other males especially if they look similar.
Unfortunately with many gobies, (and some people) you can't tell the sex

I guess i ought to add that the tank size is 43cm (17inch) cube, which affect how much available sand there is to share around
