Can Black Skirt Tetra live with Thick-lipped Gourami?
Caution — with care
Why
- Black Skirt Tetra is a fin-nipper and will shred the long/flowing fins of Thick-lipped Gourami.
- Only a narrow water hardness overlap — keep both around 6–7.5 dGH.
- Black Skirt Tetra is semi-aggressive — give the peaceful Thick-lipped Gourami plenty of space, cover and broken sight lines.
Sweet spot: both do well at 72–82°F and pH 6.5–7.5 — aim there.
Side-by-side
| Black Skirt Tetra | Thick-lipped Gourami | |
|---|---|---|
| Temperature | 70–82°F | 72–82°F |
| pH | 5.5–7.5 | 6.5–7.6 |
| Hardness (GH) | 3–15 dGH | 6–7.5 dGH |
| Adult size | 2.5" | 3.5" |
| Temperament | Semi-aggressive | Peaceful |
| Min tank | 20 gal | 30 gal |
Together, plan on at least 30 gallons.
How to make it work
- Keep the nipper in a bigger group (8+) to spread out the nipping, and avoid long-finned tankmates.
- 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.
Sort it with: GH remineraliser
