Two clown gobies 1 tank?

I have done it with zero issues. On paper you'd be fine. But just remember that every fish has a personality, and what works for some may not work for others.

if you get a pair they will be fine , I had a mated pair for close to 9 years . Still have the male , but add with caution as mine became very territorial once they started to breed in the tank .
