When your clean up crew grows up

I have a clean up crew that consists of snails, blue legs, scarlet hermite and emril crabs.
The blue legs are growing quickly and they like to kill the scarlet crabs, and now their first snail, and take their shells instead of the empty ones I provide.
My emril crab has begun to attack my feather duster.
Do people usually take these things out as they grow up and get more aggresive?
Is there a puffer that will eat crabs and not snails?

On the topic, does anyone know the general life expectancy of hermits and turbos when kept in a healthy tank?
