VerdictCAUTION

Caution. Check the issues below before buying.

Discus + Zebra Danio: Temperature window mismatch on paper. Discus needs 28–32°C and Zebra Danio needs 18–26°C. Their ranges do not overlap. Fishori still flags this as high-friction. Many keepers avoid the mix; if you attempt it, you need a very deliberate temperature and observation plan. Outcomes still depend on your tank shape, maintenance routine, and individual fish.

Next steps

Concrete changes, not "research more" filler.

  • •Discus should be kept in a group of at least 4 for best health and behaviour.
  • •Zebra Danio should be kept in a group of at least 6 for best health and behaviour.
  • •These fish cannot be comfortably housed together. Their temperature needs are incompatible.

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.

Discus + Zebra Danio — common questions

Can Discus live with Zebra Danio?
Yes, if you plan for it. The verdict is CAUTION, which means the pairing works when specific conditions are met, not by default. The first condition: Discus should be kept in a group of at least 4 for best health and behaviour.
What tank size do you need for Discus and Zebra Danio together?
Plan around 200 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?
Temperature window mismatch on paper. That is the first thing to plan around. The matching entry under assessment details on this page explains the reasoning and the numbers behind it.
What should you check before buying?
Zebra Danio should be kept in a group of at least 6 for best health and behaviour. These fish cannot be comfortably housed together. Their temperature needs are incompatible.
