Fish comparison
Dojo Loach vs Ember Tetra
How the Dojo Loach and Ember Tetra compare on care, size, water and temperament, and which fish suits your tank.
By Mike ElmiraUpdated
TL;DR, Dojo Loach vs Ember Tetra
The Dojo Loach 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 24 °C and pH 6.5 to 7, so a single tank can suit either one. Neither is harder than the other to keep, so the choice comes down to look and stocking rather than skill. If tank space is tight, the Ember Tetra needs less room to feel settled; give the Dojo Loach the nod when you have the litres to spare.
