Risks and things to watch
Amano Shrimp may be eaten or harassed
Adult amano shrimp are usually safe with small peaceful fish, but babies rarely survive. Dense moss and cholla wood give juveniles somewhere to hide. Never medicate the tank with copper.
Group requirements
Compatibility is not only about the two species getting along — each still needs its own social setup met inside the same tank.
- Celestial Pearl Danio — minimum group of 8. Budget tank space for the whole shoal, not one fish.
- Amano Shrimp — minimum group of 3. Budget tank space for the whole shoal, not one fish.
Frequently asked questions
Can celestial pearl danio and amano shrimp live together?
Possible, with conditions. Celestial Pearl Danio and Amano Shrimp can work, but this is a conditional yes rather than easy one. Read the risk section below before buying — the pairing usually fails for one specific reason, not because of general incompatibility. Plan on 16 gallons minimum.
What size tank do celestial pearl danio and amano shrimp need together?
Plan for at least 16 gallons. Celestial Pearl Danio alone needs 10 gallons and Amano Shrimp needs 10, but combined stocking needs headroom for filtration and swimming space, not just volume.
What temperature suits both species?
Both are comfortable between 72 and 79°F. Set the heater to the middle of that window and keep it stable.
What pH works for both?
Aim for pH 6.5–7.5, which sits inside both species' comfortable range.
Will amano shrimp eat celestial pearl danio?
Unlikely. At 2.0″ versus 1.0″ the size gap is not large enough for predation, though fry and juveniles are never safe in a community tank.
How should the tank be arranged?
Use plants, wood and rock to break sight lines, keep open swimming space along the front, and add the more territorial species last so it cannot claim the whole tank before the other settles in.
