yeah, the green chromis is the most ideal damsel for an
aquarium.
they do school, are peaceful, good eaters, hardy,and they swim at the
top of the water column, which is relatively rare.
i got some too i like them and im planning on getting about 15 of them just for the fact that there easy to keep and swim around together, i did have a problem with one that kept chasing my clowns but my tang sorted it for me
