3 gallon stocking ideas; if any?

[ReefGuy1234]

Just got this 3 gallon all in one. It only has a pistol shrimp pair which is fine as is because I’m planning on making this more of a coral tank however I want to add one more fish if possible. Not two just one tiny one. I was thinking about small clown goby or a small tail spot. Any problems? Or is it too risky in such a small system? Thanks

By pistol shrimp pair, do you mean a paired pistol shrimp and the yellow watchman goby in the picture?

Pair of porcelain crabs would be cool. Other inverts. That red fish that just sits. Forgot it’s name

Yeah sorry about that, that is what I meant. A ywg and pistol shrimp!

It looks like it was started with live rock from either an established system or real ocean live rock meaning you already have a copepod population. Ive had a Greissenger Goby in a tank about the same size for a couple months and with nightly phyto dosing the pod population is very high even with him. They don't eat nearly as many pods as a dragonet so that would be a choice. Only downside would be the price tag in America. Also, I haven't kept one with another Goby but i doubt they'd fight since they have different diets and don't look alike to each other. If you're considering adding a Greissenger Goby just look into how agressive they may be towards each other first because although both are docile I haven't kept two Gobies together in such a small tank. Here's mine:
