Can Black Molly live with Cardinal Shrimp?
Not recommended
Why
- Black Molly is 5.0× the length of Cardinal Shrimp — easily mouth-sized, and anything that fits in the mouth is a predator.
- Black Molly is not on the verified shrimp-safe list, so we will not recommend it over a breeding Cardinal 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.
