Cleaner shrimp are pretty alert. I see he's in a large tank with quite a bit of rock, he should be fine. In my 220g, I have a coral banded with 7 cleaner shrimp, 4 peppermint shrimp, and a blood shrimp.
I've watched him roam about in the day before. If he gets close to one of the shrimp, he'll open his claws and move towards the shrimp. However, the shrimp are smart enough to get out of the way, and the coral banded won't persue it for more than a couple of inches. I've had no issues so far.
One thing to keep in mind is that I keep the coral banded well fed. Every few days, he gets a piece of scallop that's about the size of a smartie. If he's well fed, he'll be less likely to pursue anything aggressively.
