It looks nice and healthy, I wouldn't pinch anything, but I would start to use the fruit, if you are familiar with it, then you know what to do. If not use the same as any limes or lemons. I have a small tree and it always produces a lot of fruit! because is on the side of the front yard sometimes I forget that I have it.

@silvia - Thanks! So I shouldn't wait for the fruit to fully ripen (orange)? Is this more of a pie/marmalade type of fruit or is it also good on its own as a snack?

You can use the same as any acid citrus, in salads, cooked food, marmalade, beverage like lemonade.
It is very used in the Philippines and they use it a lot!, they make a dish called pancit which is very good and sprinkle the calamondin on top.
All my acid citrus I start to use at the full size, they can be green and of course when they are fully ripened also. This way I get to use them for a longer season.
