Mixing gobies

[NanCrab]

I have a diamond goby in my 72” 125g DT. It used to be all over the tank keeping it clean but for the past several months has decided that only the right 1/3 of the tank is his and he never, ever goes to the other side of the sand mountain he created and grooms daily. Problem is the other 2/3 of the tank is disgusting. The sand on his side is spotless. So I’m thinking of adding another sand sifting goby but wondering if they will fight. This is the one I was thinking of adding:

If this won’t work I’m open for suggestions! I have a HUGE CUC Including conch snails. I don’t have a sand sifting star. I think I have most other inverts including multiple species of snails that reproduce like crazy

Yes they will fight.....if not now, later. Just a matter of time. Unless you have smaller gobies, large tank, or you have a pair to start off with.

That’s what I was afraid of

You could sell your existing and buy a pair.

Sell Riley? I think I’ll keep him. Maybe soon he will decide to venture back over to the now “dark side”.
