Can Red Rili Shrimp live with Swordtail?
Not recommended
Why
- Swordtail is 5.5× the length of Red Rili Shrimp — easily mouth-sized, and anything that fits in the mouth is a predator.
- Swordtail is not on the verified shrimp-safe list, so we will not recommend it over a breeding Red Rili Shrimp colony. It may well be fine — it simply has not been confirmed by a source, and an unverified guess is not worth the colony.
- Only a narrow water hardness overlap — keep both around 12–14 dGH.
