WHERE ARE THE PICS

I've only seen/read very limited info about there care.They are found on soft/muddy substrates,make sure you have at least a 3-4"sand bed.This genus relys on feeding rather than light for nutrition so you'll need to feed it often.I'd try burrying it in the sand,then wedging it in between 2 small rocks until it secures itself.
