Compatibility brief
Can Dojo / weather loach live with Pea Puffer?
Risky. This mix is commonly discouraged for typical setups.
Compatibility score
Profile confidence: medium
Order of checkstank volume vs adults → predation mouth gap → temperament / fin nipping → shared water windows.
150L
Combined minimum footprint reference for these two species: about 150L (larger active fish often want more length).
Dojo / weather loach (25cm adult) may treat small Pea Puffer (~3cm) as food once grown — plan adult sizes, not shop sizes.
Temperament gap (peaceful vs semi-aggressive) adds stress on top of the hard incompatibility — space and cover do not make this pairing safe.
Assessment details
Temperament difference
Pea Puffer is semi-aggressive, while Dojo / weather loach is peaceful. Expect chasing or stress unless the tank is large and heavily structured — monitor closely.
Dojo / weather loach may eat Pea Puffer
Top issueDojo / weather loach (25cm) is predatory and Pea Puffer (3cm) is small enough to be eaten. This pairing is unsafe.
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
- →Build a species-only tank for the larger fish, or restock with fish too large to be eaten at adult sizes.

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: high. Checked against several solid care sources that mostly agree.
