Can Flash Pleco (L204) live with Zebra Danio?
Caution — with care
Why
- Zebra Danio is a fin-nipper and will shred the long/flowing fins of Flash Pleco (L204).
- Very different sizes (Flash Pleco (L204) 20" vs Zebra Danio 2") — these two need different tanks, and the smaller fish will be out-competed at feeding time.
- Only a narrow water hardness overlap — keep both around 6–7.5 dGH.
Sweet spot: both do well at 72–77°F and pH 6.5–7.5 — aim there.
Side-by-side
| Flash Pleco (L204) | Zebra Danio | |
|---|---|---|
| Temperature | 72–82°F | 64–77°F |
| pH | 6.5–7.6 | 6.5–7.5 |

| Adult size | 20" | 2" |
| Temperament | Peaceful | Peaceful |
| Min tank | 125 gal | 10 gal |
Together, plan on at least 125 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.
