Can Koi Angelfish live with Red Nose Shrimp?
Caution — with care
Why
- Koi Angelfish is 4.0× the length of Red Nose Shrimp and big enough to swallow one. Some keepers get away with it in a heavily planted tank; it is a real risk.
Sweet spot: both do well at 78–82°F and pH 7–7.5 — 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.
- Add only full-grown adults — never juveniles, which will be eaten.
