Are you supplementing your Otos? Often they come from the fish store half starved and unless you have an established tank with plenty of algae (more then 7 weeks) they can starve to death.
I got plenty of diatoms growing...their tummies are bulging. They took to eating as soon as I released them and continue to clean the tank. However, I think the diatoms have a head start =0)
Anyways, I monitor them closely since they are constantly feeding.
