Aquatics

I recently added a cleaner shrimp to my 29 gallon tank and it only lived a couple of weeks. I have hermit crabs and snails in the tank without any issues. There are only 3 small fish in the tank.

Are cleaner shrimp more sensitive to water conditions? What about peppermint shrimp? Are other inverts harder/easier to keep?

Just wondering if I’m doing something wrong or need to change something. 🤷‍♂️

Thanks
