What else can I add to my tank

[mochlate]

I've got a 20 gallon reef tank.

I've got 4 small fish, some corals, some snails, some hermits and some shrimp.

What else can I add to my tank that that would add some more movement?

Heres a nicely detailed picture of the tank so far

There's another small clown hiding somewhere and an ID on that coral would be nice while we're here

Nice rockwork. I have a 30 with a few more coral pieces.

Yellow Watchman paired with a randall,
2 Clowns
Baby Tailspot
Juvenile McCoskers Wrasse
Helfrichi Firefish

I want one more too, but thing I am going to have to be satisfied and not push the bioload. They do grow after all.
My setup is very similar to yours but I have a little more rock and coral pieces so its a little more cluttered. Maybe you can get away with one more(similar size) given you seem to have more open space.

I'm looking more for critters that I can add that I can see move about the tank. Not so much fish, I think I'm at the max for fish

Sally light foot crabs?

That tank looks great man

I’m a big fan of emerald crabs. I’ve got 5 in my tank right now. 3 are males and they get huge. Mine are a good 2 inches across

I've got a ton of emeralds too.. 1 or 2 big males.. the rest are female.. I've got a 90 display and 49 gallon bow front xenia fuge..about 20 or so emeralds between the two.. but the sallys steal the show.. 2 have small pink claws.. 1 has big blue claws.. his leg span is every bit of 4 inches.. and it does some crazy acrobatic jumps to catch food and go from the rock it's on.. to the rock above it..
And thank you.. it's been a bit of a rough road.. but the tank has finally pulled through

Nothing shows movement like simple xenia

 

[reef cuber]

lol - nothing takes over a tank like xenia too!

That unknown coral looks like Montipora digitata?

 

[crawlerman]

I believe your unknown coral is a birds nest (if it is a hard coral). I have never had one, but that sally light foot crab is cool. If that birds nest is doing good, you are doing things right. It is an easier sps, but still sps. I think I would put a plating monti right on the rock below your clown. maybe a toad stool or devils hand leather on the far right.

If your into stunning colours and easy care, a scolimya, but because they can't be fragged are expensive.
