Answer
Hi Austin
You could possibly keep them in a 75g - I know an Oscar will be extremely comfortable in one. Clown knife fish should be fine as well - I am sorry I don't remember what your third one was (I am inclined to say gar).
In terms of absolute volume a 75g tank will be fine - not ideal, but you shouldn't have any problems. Make sure you get some serious filtration though - if you have a gar they like live or meaty foods - same with oscars who are messy easters. A 75g tank would be best with a canister and a bio-wheel (something like an Eheim 2215 + Emperor 400) - If you are in the US - shop around online as filters are really cheap and some petsmarts will price-match. The used market is a good idea for HOB's - or canisters IF they have media (you will find filling a canister filters gets real expensive real fast).
Hope that helps... please feel free to ask any questions you may have. Good Luck
