Compatibility brief

Can Dojo / weather loach live with Pea Puffer?

VerdictRISKY

Risky. This mix is commonly discouraged for typical setups.

Dojo / weather loach + Pea Puffer: Dojo / weather loach may eat Pea Puffer. Dojo / weather loach (25cm) is predatory and Pea Puffer (3cm) is small enough to be eaten. This pairing is unsafe. Real tanks add variables Fishori cannot model; treat this as a high-risk read, not certainty.

Size / predation

Dojo / weather loach (25cm adult) may treat small Pea Puffer (~3cm) as food once grown — plan adult sizes, not shop sizes.

Temperament / behaviour

Temperament gap (peaceful vs semi-aggressive) — can work with space, structure, and careful observation, but not a “drop and forget” mix.

Assessment details

  1. Temperament difference

    Pea Puffer is semi-aggressive, while Dojo / weather loach is peaceful. This can work with adequate space and hiding spots, but monitor for bullying.

  2. Dojo / weather loach may eat Pea Puffer

    Top issue

    Dojo / weather loach (25cm) is predatory and Pea Puffer (3cm) is small enough to be eaten. This pairing is unsafe.

  3. Narrow temperature overlap

    Dojo / weather loach and Pea Puffer have only a narrow shared temperature range. Maintaining stable water temperature will be important.

Next steps

Concrete changes, not "research more" filler.

  • Provide plenty of hiding spots and visual breaks so Dojo / weather loach can escape if harassed.
  • Dojo / weather loach should be kept in a group of at least 5 for best health and behaviour.
  • Pea Puffer should be kept in a group of at least 6 for best health and behaviour.

Try instead

  • Provide plenty of hiding spots and visual breaks so Dojo / weather loach can escape if harassed.
  • Dojo / weather loach should be kept in a group of at least 5 for best health and behaviour.
  • Pea Puffer should be kept in a group of at least 6 for best health and behaviour.
  • Build a species-only tank for the larger fish, or restock with fish too large to be eaten at adult sizes.

Plan further

Try both species in the full-stock tank check, or open either fish profile for mates lists. 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.
