Can Blue Phantom Pleco live with Flash Pleco (L204)?
Light caution
Why
- Only a narrow water hardness overlap — keep both around 6–7 dGH.
- Large size gap (Flash Pleco (L204) 20" vs Blue Phantom Pleco 7") — watch that the smaller one gets its share at feeding time.
Sweet spot: both do well at 75–82°F and pH 6.5–7.6 — aim there.
