I'll go a step further than that. There is no guarantee snails and crabs will do any sort of maintenance for you, regardless what the LFS
(who's business is to sell livestock and components) says. "Cleanup crews" are completely unnecessary, and the name was made up by livestock retailers, and it's doing what it's meant to do- make people buy creatures just to starve them to death, and/or, like in your case, place them in close proximity with known predators.
Inverts are in no way a buffer to skip necessary tank husbandry.
