Avoid
Pea Puffer and Cherry Shrimp compatibility verdict
Short answer: No, this pairing should usually be avoided. Plan for at least 10 gallons before adjusting for group size, filtration, and aquascape layout.
shrimp risk: Pea Puffer is not considered safe with dwarf shrimp.
aggression risk: Aggression or territorial behavior needs extra space, cover, and careful observation.
predator/prey risk: Pea puffers hunt small invertebrates.

Data confidence: high
shrimp risk: Pea Puffer is not considered safe with dwarf shrimp.
aggression risk: Aggression or territorial behavior needs extra space, cover, and careful observation.
predator/prey risk: Pea puffers hunt small invertebrates.
warningProtect invertebrates from predatory fish and unstable new tanks.
This verdict assumes normal social groups, not one stressed specimen. Cherry Shrimp should be planned at 10+ before judging long-term compatibility.
Shrimp and fry safety
For shrimp-heavy tanks, check adult shrimp and shrimplet risk separately. A fish may ignore adult shrimp but still hunt babies, molting shrimp, or stressed individuals.
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
Pea Puffer and Cherry Shrimp use different swim zones, but feeding time and open sightlines can still change behavior. Start with at least 10 gallons, then use hardscape, tall plants, and separated feeding zones to reduce chasing before it becomes a pattern.

Common Questions
Can Pea Puffer live with Cherry Shrimp?
No, this pairing should usually be avoided. Main reasons: shrimp risk, aggression risk, predator/prey risk.
What tank size do Pea Puffer and Cherry Shrimp need?
Plan at least 10 gallons before adjusting for group size, filtration, and aquascape layout.
Troubleshooting aggression between Pea Puffer and Cherry Shrimp
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 Pea Puffer and Cherry Shrimp
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.
