I am starting to stock a 30 gallon tank. My original plan included Bleeding Heart Tetras (8-10) and Glowlight Tetras (8-10). Just for the color combination, I am thinking about Cherry Barbs instead of the Glowlight Tetras. Does this combination work well enough? Should I cut back on the number since Cherry Barbs are a little bigger than Glowlight Tetras? Thanks! Stay cool if you're in a hot place, like me. And hydrated!!!
