- Hardness both tolerate: 6–8 dGH
- Recommended combined tank: 8 gallons or larger
Risks and things to watch
Nerite Snail may be eaten or harassed
Adult nerite snail 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.
- Chili Rasbora — minimum group of 8. Budget tank space for the whole shoal, not one fish.
- Nerite Snail — no group requirement; single specimens are fine.
Frequently asked questions
Can chili rasbora and nerite snail live together?
Yes — compatible. Chili Rasbora and Nerite Snail are a good match. They share a workable temperature and pH window, neither is large enough to threaten the other, and temperaments are compatible. Give them at least 8 gallons once both group requirements are met.
What size tank do chili rasbora and nerite snail need together?
Plan for at least 8 gallons. Chili Rasbora alone needs 5 gallons and Nerite Snail needs 5, but combined stocking needs headroom for filtration and swimming space, not just volume.
What temperature suits both species?
Both are comfortable between 75 and 82°F. Set the heater to the middle of that window and keep it stable.
What pH works for both?
Aim for pH 7–7, which sits inside both species' comfortable range.
Will nerite snail eat chili rasbora?
Unlikely. At 1.0″ versus 0.7″ 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.
