Cleaner shrimp.

[Pier Pressure]

I have two cleaner shrimp who are always full of eggs. When the eggs are ready, they seem to move to the outside of the back-end of the cleaner shrimp and you can see them on the outside. Eggs look bright green while inside but are white once they move out. Then I think the eggs just hatch and you have millions of little shrimp. I once caught a feeding frenzy in my tank and can advise that the cleaners are not good parents and are quite happy to eat their young.
