What fish for 20g

[clownfishluvr123]

So I have a 20g saltwater tank set up. It’s been running for some time. I currently have a clownfish and a royal gramma. How many more fish can I add and what kind of fish should I add? I was thinking of getting another clownfish and a diamond goby. Is this okay?

I’d add 1 more fish. I have a clown, black cap basslett and flame hawk in mine and everything seems to mesh well.

I’d say yes to the clown and no to the goby. The goby will need more sand surface area to do well.

If the clown has been solo for a while get a small male. Personally I'd go for a watchman goby and pistol shrimp

I'd get something that eats algae, bi color blend, algae blenny, etc. Utilitarian fish are super helpful.
