Can Harlequin Rasbora live with Chocolate Shrimp?
Light caution
Why
- Adult Chocolate Shrimp are safe with Harlequin Rasbora, but it will take newly hatched shrimplets. Give the colony a thick mat of moss and let it reach 30-50 adults before adding fish, and it will still grow — just slower.
- Harlequin Rasbora will eat Chocolate Shrimp shrimplets. The colony still grows if there is moss or another dense hiding place for the babies.
- Only a narrow pH overlap — keep both around 7.5–7.5.
Sweet spot: both do well at 74–80°F and pH 7.5–7.5 — aim there.
