Can Flash Pleco (L204) live with Red Nose Shrimp?
Light caution
Why
- Flash Pleco (L204) is much larger than Red Nose 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 73–82°F and pH 7–7.6 — aim there.

How to make it work
- Keep a large, established shrimp colony in a heavily planted tank with moss and cover so enough survive to breed.
- Target the overlapping water-parameter range and acclimate slowly.
