Can Ghost Shrimp live with Flash Pleco (L204)?
Light caution
Why
- Flash Pleco (L204) is much larger than Ghost Shrimp but is not a shrimp hunter — it may take a shrimplet or clean up a moult. Adults are safe with cover.
- Only a narrow water hardness overlap — keep both around 6–7.5 dGH.
Sweet spot: both do well at 72–82°F and pH 6.5–7.6 — aim there.

How to make it work

- Target the overlapping water-parameter range and acclimate slowly.
