Can Blue Bolt Shrimp live with Oscar?
Not recommended
Why
- Oscar hunts shrimp and is 16.0× the length of Blue Bolt Shrimp — it will eat them.
- Oscar is not on the verified shrimp-safe list, so we will not recommend it over a breeding Blue Bolt 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.
- Almost no shared temperature: Blue Bolt Shrimp wants 68–74°F and Oscar wants 74–81°F, so only 74°F suits both — too fine a margin to actually hold.
- Only a narrow water hardness overlap — keep both around 5–5 dGH.
