3 pairs assessed
Ember TetraPygmy Corydoras

Ember Tetra + Pygmy Corydoras

All recorded checks pass for this pair.

Compatible

Same water type

Both profiles are freshwater.

Shared pH 6.2–7.4

The recorded planning ranges overlap. Aim near the middle rather than either extreme.

Shared temperature 23–26°C

The recorded temperature ranges overlap.

Base tank threshold met (40L+)

This is the larger species-level minimum only; quantity, territory, filtration and swimming space can require more.

Recorded community match

At least one established FishSnap profile lists this pairing as a starting point for community planning.

No obvious size-based predation flag

Recorded adult lengths are about 2 cm and 3.2 cm. Individual behaviour still matters.

Ember Tetra + Chili Rasbora

Both profiles are freshwater.

Shared pH 5.5–7

How FishSnap reaches this assessment

Every unique pair is checked against water type, pH overlap, temperature overlap, the larger recorded minimum tank, curated community matches, social/aggression flags and adult-size predation risk.

A green result means the recorded checks pass; it is not a guarantee. Aquascape, filtration, sex, maturity, territory and individual temperament can change the outcome. The base tank value is not a stocking-capacity calculation.

Use this as a welfare-first planning screen before purchase. Introduce livestock gradually, quarantine when appropriate and keep a separation plan for territorial or predatory fish.
