peaceful~2.5cm
VerdictRISKY

Risky. This mix is commonly discouraged for typical setups.

Assassin Snail + Nerite Snail: Known incompatible pairing. Assassins hunt other snails; a nerite's operculum helps but does not make it safe, and groups will wear one down. Keep assassins away from snails you value. Real tanks add variables Fishori cannot model; treat this as a high-risk read, not certainty.

Assessment details

  1. Known incompatible pairing

    Top issue

    Assassins hunt other snails; a nerite's operculum helps but does not make it safe, and groups will wear one down. Keep assassins away from snails you value.

  2. Assassin Snail eats snails

    Assassin Snail preys on aquarium snails — Nerite Snail will be hunted, not cohabited. Do not mix a valued snail with this species.

  3. Compatible temperature range

    Both fish can comfortably share similar water temperatures.

Plan further

Check each species’ mates list, size the glass, then verify the full stock in the builder. Methodology explains how verdicts are produced.

Individual fish vary in personality. Fishori uses conservative hobby rules. Observe any new introduction closely, feed thoughtfully, and keep a quarantine or backup plan. This is not veterinary advice.

Profile data confidence: medium. Typical care sources — real tanks still vary.

Can Assassin Snail live with Nerite Snail?
For most keepers, no. The verdict is RISKY: at least one check fails hard for a typical home tank. Choose a different pairing, or read the assessment details on this page to see exactly what fails before deciding.
What tank size do you need for Assassin Snail and Nerite Snail together?
Plan around 30 litres as the working minimum. That figure comes from each species' published minimum and their group needs, and it assumes adult sizes, not shop sizes.
What's the main risk?
Known incompatible pairing. That is the check that fails outright for this pair. The matching entry under assessment details on this page explains the reasoning and the numbers behind it.
