How to make it work
- Add the calmer, smaller fish first, and the dwarf gourami last.
- Use plants, wood or rocks to break up the view across the tank. Fish that cannot see each other all day fight less.
- Watch closely for the first week. Torn fins, hiding or a fish that stops eating mean it is not working.
- Keep a spare tank or a divider ready, so you can separate them the same day.
Questions and answers
Can neon tetras and dwarf gouramis live in the same tank?
Yes, usually. Neon tetras and dwarf gouramis like the same water: 72–79 °F (22–26 °C) and a pH of 6–7.5. Neon tetras spend their time in the middle and dwarf gouramis near the top, so they stay out of each other's way. Dwarf gourami can be pushy, so watch for chasing in the first week.

At least a 20 gallon long tank, which carries about 13 neon tetras and 1 dwarf gourami comfortably.
