I guess lets look at this slightly differently then...
Since i've never spoken to you, and don't know how long you have been into fish keeping, it maybe a good idea to give us some basic background info about your fish keeping history, such as how long you been keeping fish, and what are some of the fish you kept in the past?
Once you give us some basic info, maybe we can help you decide what to stock...
go to a lfs and see what they have. Find a few fish you like, post them here and do a little research on them, build your setup around the fish you like.
Since you have a snakehead, im guessing you'll probably need a reasonably size fish, that can stand up for itself to make sure it wont end up as dinner...
Im just thinking if maybe some type of large chiclid would work?
