Likely compatible with conditions
Data confidence: medium
- compatibleKribensis and Neon Tetra appear to have compatible basic freshwater ranges and behavior requirements when normal husbandry needs are met.
Can Kribensis live with Neon Tetra?
Troubleshooting community setups: see the compatibility result using temperature, pH, GH/KH, adult size, behavior, schooling needs, and predator/prey rules.
Likely compatible
Kribensis and Neon Tetra compatibility verdict
Short answer: Likely, when tank size, group needs, and water parameters are handled. Plan for at least 30 gallons before adjusting for group size, filtration, and aquascape layout.

Schooling and group-size requirements
This verdict assumes normal social groups, not one stressed specimen. Neon Tetra should be planned at 6+ before judging long-term compatibility.
Real-World Experience
Textbook score vs observed behavior
A compatibility score checks adult size, temperature, pH, hardness, temperament, and tank volume. Real tanks add variables the score cannot see directly: feeding aggression, cave ownership, plant cover, and whether fish can constantly see each other.
Line-of-sight and swim-zone pressure
Kribensis and Neon Tetra use different swim zones, but feeding time and open sightlines can still change behavior. Start with at least 30 gallons, then use hardscape, tall plants, and separated feeding zones to reduce chasing before it becomes a pattern.

Confidence: medium. Aggression, predator/prey, shrimp risk, schooling, and tank size rules are evaluated from curated freshwater attributes.
Conditions for success with Kribensis and Neon Tetra
Problems can happen even when the gallon number is technically adequate. Check feeding order, repeated access to the same cave or plant mass, school size, and whether the aquascape gives either fish a direct line of sight across the whole tank.
Bottom dweller competition between Kribensis and Neon Tetra
If either species uses the lower half of the tank, add more broken sightlines and avoid placing all food in one corner. Bottom pressure is more about usable floor space than total water volume.
How to break line-of-sight to reduce aggression
Use tall plants, rock piles, driftwood, and separate feeding stations so a dominant fish cannot patrol one open lane from end to end.
