Can Black Molly live with Snowball Shrimp?
Caution — with care
Why
- Black Molly is not on the verified shrimp-safe list, so we will not recommend it over a breeding Snowball 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.
- Black Molly is 4.0× the length of Snowball Shrimp and big enough to swallow one. Some keepers get away with it in a heavily planted tank; it is a real risk.
- Black Molly will eat Snowball Shrimp shrimplets. The colony still grows if there is moss or another dense hiding place for the babies.
- Only a narrow water hardness overlap — keep both around 12–14 dGH.
Sweet spot: both do well at 72–78°F and pH 7–7.8 — aim there.
Side-by-side
| Black Molly | Snowball Shrimp | |
|---|---|---|
| Temperature | 72–82°F | 65–78°F |
| pH | 7–8.5 | 6.5–7.8 |
| Hardness (GH) | 12–30 dGH | 4–14 dGH |
| Adult size | 4" | 1" |
| Temperament | Peaceful | Peaceful |
| Min tank | 30 gal | 5 gal |
Together, plan on at least 30 gallons.
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.
- Target the overlapping water-parameter range and acclimate slowly.
