Gobies: High Fin and Diamond

[Chitownpw]

I have a high fin goby paired with a snapping shrimp. I want to get a diamond/sand shifting goby. I have a 90 G. I also have a mandarin, among other fish. Thoughts on whether issues would arise among the gobies - in particular, the diamond and high fin?

I have a pair of high fins that live with a pair of randalli pistol shrimp. They don't interfere with anybody unless they get too close to their burrow. And even then they rather retreat into their holes than start a fight.

I also have a pair of mandarins and they pretty much ignore all other fish - literally treat them like air. They are toxic and not worried that someone takes a bite of them. In fact the only thing mandarins are paying attention to are other mandarins.

As for the sand sifting goby - make sure you deworm them well. They almost all come with a whole zoo of intestinal parasites that will ultimately kill them. Several rounds of PraziPro and Metronidazol are mandatory with them.
