Best single fish for 55g

You can scratch the Clown Knife species unless its just a grow out tank or plan on selling rather soon.

I would look into a small species of Piranha or similar... School of Exodons, wimple piranha, anubias with german rams or the only flowerhorn I like... Super Red Texas (if its a FH Lol). Wolf fish are nice but not really show pieces... they are similar to bichirs imo. Not enough movement for my taste.
 
depending on the way the tank was built... royal knife fish barely get 2 foot max in captivity thats over like 3 years. Raoyal knife should be fine if the width is adleast 18 inch as usual 55g's are.

Usual 55's are 12" wide regular 75's are 18" wide
