Can Honey gourami live with Neon tetra?

Temperature. Honey gourami does best at 23–27 °C (73–81 °F) and Neon tetra at 21–25 °C (70–77 °F). They share 23–25 °C.

Water. Their pH ranges overlap at 6–7.

Temperament and size. Honey gourami is peaceful and grows to 5.5 cm; Neon tetra is peaceful and grows to 3 cm. Honey gourami swims at the top and Neon tetra at the mid, which spreads them out.

Tank size and groups. Plan on at least 20 US gallons, the larger of the two cautious minimums. Keep Honey gourami in a group of 4+. Keep Neon tetra in a group of 8+. A starter mix of 4 Honey gourami and 8 Neon tetra in 20 gallons uses about 58% of the tank’s bioload capacity under our rules and grades A.

Keeping them together

• Feeding: both feed in open water. Feed small amounts two or three times a day so the slower eater gets its share.
• Aquascape: both are calmer with cover. Plants and floating cover make shy fish come out more, not less.
• Group size: a full group is not optional. A schooling fish kept in too small a group is stressed and more likely to nip or hide.
• Shrimp and snails: neither is a known invertebrate eater, but baby shrimp can still be eaten. Dense moss helps.
• Adding them: add the calmer species first and let it settle for a week or two before adding the other, and only once your tank has cycled.
