Re-stocking fish and inverts and would like some input.

[jjudkins1]

Hi all. I have a 20g cube mixed reef tank at 3 years age that I just started to re-stock because prior fish were getting too large for the tank. I am wondering if anyone has kept a yasha goby and a yellow rose (antenna) goby together in a nano and if so is it ok to get more than 1 pistol shrimp, one for each goby? I am guessing no. Also, I have a small ocellaris clown and a pajama cardinal and 2 cleaner shrimp and an emerald crab. My nutrients stay low, almost undetectable while running a skimmer. I was planning on adding a tailspot blenny, clown goby or pigmy hawkfish and another ocellaris clown fish. This seems like a lot of fish to me, but as long as the nutrients are staying low I am thinking that I am ok right? Any major concerns about the combination of fish and inverts I am chasing? I have done my research but still not sure. Thanks

4-6 fish is typically max for your size of tank.
