Suggestion for next fish

[smc03]

Looking for suggestions on my next fish add.
I have a 9 month old Max E170 tank (45g total / DT 37g) . I have a few corals (taking it slow since this is my first reef tank), But any fish I add will would need to be reef safe since I plan to add a lot more coral.

Today I have:
1 clown fish
1 royal gramma
1 6 line wrasse

I thought about adding a lawn mower blenny, and while my tank has going through various ugly stages with algae, generally I’ve been able to keep it under control so worry a algae blenny might not have enough to eat (or I’d have to supplement for him).

Ideas in what type of fish I should consider next that would be compatible And size appropriate? Also - how many more fish could I safely add? Would two more (if similar size to those of have now) or would 5 fish be pushing it?

I’ve got a 30 gallon and IMO you could add a fire goby, a blenny and a dwarf angel comfortably

Pajama cardinals are hardy, docile and eerily attractive. I have one named Francis Nelson Stine (Frank N. Stine) cause he looks like he was put together from at least 3 different fish. I've had him for about 3 and a half years.

A goby/shrimp pair would make good additions. Or perhaps a hawkfish.

Thanks everyone for the suggestions. Great ideas. I really would love a dwarf angel but I’m worried about it going after corals.

Ime they only go after corals when they don't have good access to algae / seaweed I've had mine for a few months at it only picked at my clam shell occasionally or the setiatopora when I recently fragged it I think it was picking at the "scab" but no damage done
