Fish comparison
Kribensis vs Neon Tetra
How the Kribensis and Neon Tetra compare on care, size, water and temperament, and which fish suits your tank.
By Mike ElmiraUpdated
TL;DR, Kribensis vs Neon Tetra
The Kribensis and the Neon 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 24 to 26 °C and pH 6 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 Neon Tetra needs less room to feel settled; give the Kribensis the nod when you have the litres to spare.

What to plan for
- Neon Tetra schools, stock at least 10You've planned for 1 neon tetra. Neon Tetra need a group of at least 10 to feel safe and shoal naturally, below that they're stressed and lose colour. Dial up the count, or remove the species.
- 67% 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.

Can you keep Kribensis and Neon Tetra together?
Yes. Their temperature and pH ranges overlap around 24 to 26 °C and pH 6 to 7, so one set of water conditions keeps both comfortable. Match group sizes and cover the usual planted-tank basics and they share a tank fine.
Which is easier to keep, the Kribensis or the Neon Tetra?
They sit at the same care level, both beginner-friendly, so neither is the obvious beginner pick. The decision is really about the look you're after.
