Can Black Molly live with Typhoon Pleco?
Caution — with care
Why
- No overlapping water hardness: Black Molly wants 12–30 dGH but Typhoon Pleco wants 6–7.5 dGH.
- Typhoon Pleco is semi-aggressive — give the peaceful Black Molly plenty of space, cover and broken sight lines.
- Large size gap (Typhoon Pleco 12" vs Black Molly 4") — watch that the smaller one gets its share at feeding time.
Sweet spot: both do well at 75–82°F and pH 7–7.6 — aim there.
Side-by-side
| Black Molly | Typhoon Pleco | |
|---|---|---|
| Temperature | 72–82°F | 75–84°F |
| pH | 7–8.5 | 6.5–7.6 |
| Hardness (GH) | 12–30 dGH | 6–7.5 dGH |
| Adult size | 4" | 12" |
| Temperament | Peaceful | Semi-aggressive |
| Min tank | 30 gal | 125 gal |
Together, plan on at least 125 gallons.
How to make it work
- 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
