Should be fine.
I have read that they like groups and only grow to 3" while the Tobacco Bass gets up to 7" and hates all tankmates. Would a Chalk Basslet bother the tankmates, the only ornamental inverts will be my Pistol shrimp, Crabs, Sea Star, and a Feather Duster, will it bother any of them?It's considered to be a hardy fish. A mixed meaty diet (ie LRS Reef Frenzy) would be perfect for them and honestly I recommend Reef Frenzy as an all in one food source for your tank anyways. Great for the fish, corals and inverts. They can be somewhat assertive to tank mates. The bigger ones can also eat smaller shrimp, so be aware of that as it grows.
