| Factor | Pearl Gourami | Honey Gourami | Assessment |
|---|---|---|---|
| Water temperature | 77–82°F | 72–82°F | Overlap 77–82°F |
| pH | 6–7.5 | 6–7.5 | Overlap 6–7.5 |
| Hardness | 5–15 dGH | 4–15 dGH | Overlap 5–15 dGH |
| Adult size | 4.5″ | 2.0″ | 2.2× difference |
| Temperament | Peaceful | Peaceful | Both peaceful |
| Swim level | Top | Top | Same zone |
| Minimum tank | 30 gal | 10 gal | Together: 36 gal+ |
Shared water parameters
- Temperature both tolerate: 77–82°F
- pH both tolerate: 6–7.5
- Hardness both tolerate: 5–15 dGH
- Recommended combined tank: 36 gallons or larger
Risks and things to watch
Both occupy the top zone
Competition for space and food is higher when two species share the same layer. Increase footprint rather than height.
Group requirements
Compatibility is not only about the two species getting along — each still needs its own social setup met inside the same tank.
- Pearl Gourami — no group requirement; single specimens are fine.
- Honey Gourami — no group requirement; single specimens are fine.
Frequently asked questions
Can pearl gourami and honey gourami live together?
Yes — compatible. Pearl Gourami and Honey Gourami are a good match. They share a workable temperature and pH window, neither is large enough to threaten the other, and temperaments are compatible. Give them at least 36 gallons once both group requirements are met.
What size tank do pearl gourami and honey gourami need together?
Plan for at least 36 gallons. Pearl Gourami alone needs 30 gallons and Honey Gourami needs 10, but combined stocking needs headroom for filtration and swimming space, not just volume.
What temperature suits both species?
Both are comfortable between 77 and 82°F. Set the heater to the middle of that window and keep it stable.
What pH works for both?
Aim for pH 6–7.5, which sits inside both species' comfortable range.
Will pearl gourami eat honey gourami?
Unlikely. At 4.5″ versus 2.0″ the size gap is not large enough for predation, though fry and juveniles are never safe in a community tank.
How should the tank be arranged?
Use plants, wood and rock to break sight lines, keep open swimming space along the front, and add the more territorial species last so it cannot claim the whole tank before the other settles in.
