Blue Chromis

They should be available in every possible LFS. They are most probably the most traded fish in this hobby (and the cheapest too). If you can't find any in an LFS, run away from there. JK But they should be available on regular basis

And as far as I know, they are one of the most docile inexpensive fish out there in the hobby (and also the ocean). And I heart that odd numbers always work best for them.
