Cherry barbs vs Ember tetra?
I have an unstocked 20gal high and wanted advice. The fish I am most excited about is dwarf corydoras but intend to add them last as they're reported to be sensitive to changing water parameters. I intend to get a pair of dwarf or honey gourami as a centerpiece surface fish. I need help picking a schooling middle level fish.
I like the idea of adding a pop of color against my black sand substrate and green java ferns with ember tetras or cherry barbs. Has anyone kept both? How do they compare to each other? Color, personality, schooling, aggression, hardiness?
I'd rank myself as having progressed from novice to determined beginner. I'd like something colorful that will school and neither how nor bully anyone. Recommendations welcome. Water is fairly hard despite driftwood and temperature is 75*F.
