Breeding the Shrimp is really easy. Just get two Cleaners of the same specie and they'll breed.
Raising the larvae is difficult & time consuming. They are so delicate that just bumping the will fatally injure them. Out of thousand of fry I managed a single Scarlet Cleaner. Peppermint Cleaners are a lot easier so I recommend you start with them.
A round container with a small light pointing right at the middle will keep the larvae from going to the bottom or the sides. This will allow you to put a sponge filter at the bottom side of the container.
The good news is that they can chew. This means they can hold onto a pretty big piece of food and chew on it all day. The bad news is that their limbs are so weak they can barely hold on to even new born Brine Shrimp. A two day old Brine Shrimp is too strong for them. A combination of newly hatched brine shrimp and crushed flaked fish food works.
Other bad news is that everything eats them. Clownfish, Feather Dusters, Hydroids, even their parents will eat them. Actually they will even eat each other if there's a large difference in size.
