By Mike ElmiraUpdated
TL;DR, Cherry Barb vs Ember Tetra
The Cherry Barb and the Ember Tetra come up together a lot when people are choosing a fish, and they are close enough to weigh side by side. Both are happy somewhere around 23 to 27 °C and pH 6 to 7, so a single tank can suit either one. The Cherry Barb is the more forgiving of the two, which matters if this is an early tank, while the Ember Tetra rewards a bit more attention. If tank space is tight, the Ember Tetra needs less room to feel settled; give the Cherry Barb the nod when you have the litres to spare.

What to plan for
- Cherry Barb schools, stock at least 6You've planned for 1 cherry barb. Cherry Barb need a group of at least 6 to feel safe and shoal naturally, below that they're stressed and lose colour. Dial up the count, or remove the species.
- Ember Tetra schools, stock at least 8You've planned for 1 ember tetra. Ember Tetra need a group of at least 8 to feel safe and shoal naturally, below that they're stressed and lose colour. Dial up the count, or remove the species.
- No bottom teamNo bottom-dwelling fish or shrimp. A small group of corydoras or a shrimp colony picks up leftover food and keeps detritus in check.
- 100% of your fish swim in the midHeavy concentration in a single zone. Spreading stocking across all three levels makes the tank read fuller for the same bioload.
