Can Opaline Gourami live with Licorice Gourami?
Caution — with care
Why
- Opaline Gourami may eat Licorice Gourami; add only full-grown adults, because juveniles and fry will be picked off.
- No overlapping water hardness: Opaline Gourami wants 5–20 dGH but Licorice Gourami wants 0–4 dGH.
- Opaline Gourami and Licorice Gourami are both labyrinth fish — they claim the same surface territory and will fight, especially between males.
- Only a narrow pH overlap — keep both around 6–6.
- Opaline Gourami is semi-aggressive — give the peaceful Licorice Gourami plenty of space, cover and broken sight lines.
Sweet spot: both do well at 73–82°F and pH 6–6 — aim there.
Side-by-side
| Opaline Gourami | Licorice Gourami | |
|---|---|---|
| Temperature | 72–82°F | 73–82°F |
| pH | 6–8.5 | 4–6 |
| Hardness (GH) | 5–20 dGH | 0–4 dGH |
| Adult size | 6" | 1.4" |

| Min tank | 30 gal | 5 gal |
Together, plan on at least 30 gallons.
How to make it work
- Add only full-grown adults — never juveniles, which will be eaten.
- Target the overlapping water-parameter range and acclimate slowly.
- Use a larger, well-decorated tank with sightline breaks, keep everyone well-fed, and add the calmer fish first.
