Water parameter overlap
Behavior and space
A classic schooling tetra that is most confident in a proper group and subdued community settings. Tall-bodied cichlids that need vertical room and may prey on very small fish as they mature.
A compatibility answer should also consider the actual tank dimensions, number of each fish, filtration, planting and other occupants. Two species can be reasonable together in a long, structured aquarium yet become a poor pairing when compressed into a small footprint.
Common questions
Can Neon Tetra live with Angelfish?
The StockingLab verdict is avoid: Angelfish may view a much smaller Neon Tetra as prey when fully grown.
Do their temperatures overlap?
24–26°C / 75.2–78.8°F shared range.
Should I trust compatibility calculators completely?
No. Individual behavior, sex ratios, breeding condition, aquascape and tank size can change the outcome. Use the result to identify risks, then verify care requirements before purchase.
