Can Longfin Bristlenose Pleco live with Flash Pleco (L204)?
Light caution
Why
- Only a narrow water hardness overlap — keep both around 6.5–7.5 dGH.
- Large size gap (Flash Pleco (L204) 20" vs Longfin Bristlenose Pleco 5") — watch that the smaller one gets its share at feeding time.
Sweet spot: both do well at 72–82°F and pH 6.5–7.6 — aim there.
