Well, I must have a mighty docile one, because the tetras and barbs have
been with him for the better part of three years. Granted they are the size
of one of his side fins, he could care less about them, and them of him. 
Thank you for your other information. One last question. If I get the
lionhead food and also put in some regular flake food for the smaller fish,
would this be okay? The oranda is a pig and usually gets to the food first,
with the smaller fish catching what is floating down. Is the lionhead a
floating food? And just how long can an oranda live considering he is
already 3 years old?
Thanks.
You will probably do fine there. I would recommend a food such as
Spirulina 1 for your flake food, as this food is alos beneficial to
your oranda.
The Lionhead food is a sinking pellet.
As for longevity, there are a lot of factors that go into this,
including tank size, feeding, even chemistry. But in general Orandas
live a while as fish go, about 15-20 years in well cared for aquariums
(sometimes much longer in ponds).
