Compatibility brief
Can Ember Tetra live with Ropefish / reed fish?
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.
200L
Combined minimum footprint reference for these two species: about 200L (larger active fish often want more length).
Ropefish / reed fish (30cm adult) may treat small Ember Tetra (~2cm) as food once grown — plan adult sizes, not shop sizes.
Assessment details
Compatible temperaments
Both Ember Tetra and Ropefish / reed fish share a peaceful temperament.
Ropefish / reed fish may eat Ember Tetra
Top issueRopefish / reed fish (30cm) is predatory and Ember Tetra (2cm) is small enough to be eaten. This pairing is unsafe.
Compatible temperature range
Both fish can comfortably share similar water temperatures.

Next steps
Concrete changes, not "research more" filler.
- •Ember Tetra should be kept in a group of at least 8 for best health and behaviour.
- •Ropefish / reed fish reaches ~30cm: tank length and turning room matter more than the litre number. A tall, short tank of the same volume is not equivalent.
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.
