Help me get rid of some of the yellow

[Hinds04]

2 firefish (unsure of which one)
1 midas blenny (yellow/gold)
1 threadfin butterfly (yellow/white/black)
1 royal gramma (pink/yellow)
1 percula clown (orange/white/black)
1 yellow tang (yellow)
1 flame angel (red/black)

2 emerald crabs
1 ruby crab
1 pom pom crab
1 sally lightfoot
3 blood red shrimp
5 blue leg
20 trochus
20 nassarius

Planning for my future 75 gallon. I want to replace either the blenny or the butterfly with something peaceful with more color. Any ideas?

Cleaner Goby? They are neon blue with with black. Quite a stunning fish and they also clean your other fish. I'd swap the Midas for it.
