you seem to have a lot of space to do a lot with. more clown loaches as they prefer to be in a group (larger the better), you will see their behaviour change when they have company.
their is almost an infinite amount of things you can do. you may have to be more specific and say what your tastes in fish are, ie large, small, shoalers, single specimens, specific families of fish like tetras, cichlids, botia etc.
Two Clown Knives would need 400 gallons+, as they are HUGE (up to three feet) and can be aggressive to one another. Not only that, but they would devour many of your fish.
I would get more loaches at the moment (at least five of a species, they are schooling fish), and then you can explore more options.

A 3-4" Black Ghost Knife will grow with your smaller fish, and when it's huge, your loaches will be too big to eat. Average dojos get somewhere around 6"-7" and clowns get 7"-10"... way too big for even a maxed-out 18" black ghost. I agree about the clowns... they have massive mouths and grow fast. Bichirs are awesome fish to watch, but if you want something a bit less aggressive, ropefish are amazing. They'll get to 2'-3' but work well in community tanks with fish larger than feeder goldfish.
I picked up a peppered firetail botia [aka Blyth's loach] a while ago http://www.loaches.com/species-index/syncrossus-berdmorei which is now 5"... Tiger Botias are kind of aggressive, but we found one that is more interested in food than anything else and works well in our community.
Go for some more cichlids. Satanoperca, Geophagus, and Heros are some great families to look into. They are all gorgeous fish, not aggressive, and will definately add spunk to the tank.
DEFINATELY focus on getting some more clown loaches though. Build them up gradual though or you may possibly break your pocket book! EESH!
