I have a 90 gallon tank stocked as follows:

2 clowns
1 yellow watchman goby paired with a tiger pistol shrimp
1 6 line wrasse
1 bubble tip anemone
various snails and hermits
various soft and lps corals / may add some SPS in the future

Looking to add a new fish and would love some input on what to add. I've been researching but nothing is jumping out at me. Thoughts?
