Fish Suggestions for 20 Gallon Long?

[Tylerismale]

Hello everyone! I have a 20-gallon long and at the moment for fish, I only have a clown and a yellow clown goby. I am wondering if anyone has recommendations on any other fish I could add. I also want to add another clown so I have a pair, however, I know that clowns are poopy heads so how should I go about that? (I have an Ocellaris and plan on getting another Ocellaris). Also, my filtration is for 50 gallons and I have a protein skimmer.

Another clown should be OK as long as it looks the same as your current one. How long has the other clown been in there?
you can also look at a 6 line wrasse, maybe an angel or 2. I love the blue and orange ones.
could also go for a shrimp or 2.

You could add a Blenny, (Lawnmower or Tailspot) always interesting to watch.

He has been in there for a couple of weeks now. I also think he might be still very young cause he's literally only 1.5 inches.

I should also mention that I am going for a reef tank and have macroalgae
