Compatibility brief
Can Discus live with Zebra Danio?
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.
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).

- •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
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.
Profile data confidence: high. Based on multiple reputable aquarium care sources with strong agreement.
