Ready for fish yet??

It's been two weeks since we set up our 90g with a 55g sump/refugium. All water parameters continue to look good:
Ammonia = 0
Nitrite = 0
Nitrate = 0
Salinity 1.022
PH = 8.2
Calcium = 440
KH = 10
Phosphate = 0

We added a full CUC on Tuesday. All doing well and eating away at the algae. Added Chaeto and red mangrove in the refugium and both doing well.

I don't wan't to move too fast, but considering the live rock was kept alive, and all parameters continue to look good, and the CUC, including 3 existing Cucumbers are alive and well, is it time to add fish? What say you?

Thanks for the thoughts!
