Next Invert for my tank

[ArowanaLover1902]

My tank is a 35 gallon mixed reef, I have all kinds of corals. My current stocking of livestock is:
- 1 False Percula
- 1 Royal Gramma
- 1 Yellow Watchman Goby
- 1 Lawnmower blenny
- 1 Feather Duster
- Several Hermit Crabs
- 1 Peppermint Shrimp (if he is a problem I can move him to the sump)
- 1 Emerald Crab
- 1 Anemone Crab (I'm not sure still, don't see him much)
- Various snails
What should I add next? I'd love to have something that is good to watch. The goby would be cool to pair with a pistol shrimp. Could I possible keep two of the shrimp, the tank is shallow and long, lots of room for any burrowing inverts? I don't know much about the pom pom, fire shrimp, banded coral shrimmp, or anything about starfish. Any advice is appreciated, thanks

You should definitely have a cleaner shrimp I think. They are fun to watch and are very beneficial. I also like my fire shrimp but he hides most the time. My banded serpent star is pretty neat as well as pin cushion urchin. Lots of options though

I added 3 sexy shrimp recently and love them.
