Can Koi Angelfish live with Crystal Red Shrimp?
Not recommended
Why
- Koi Angelfish is 6.0× the length of Crystal Red Shrimp — easily mouth-sized, and anything that fits in the mouth is a predator.
- Koi Angelfish is not on the verified shrimp-safe list, so we will not recommend it over a breeding Crystal Red 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.
- No overlapping temperature: Koi Angelfish wants 78–84°F but Crystal Red Shrimp wants 68–76°F.
