I think i have made up my mind of what i want to put in my 55 gal aquarium. I have been doing a lot of fish searching and i came across freshwater barracudas. 

. So far i have found different sites with information on them and tank size needed which has gotten me a little confused because it varies a lot.
http://www.aquaticcommunity.com/fish/hujeta.php says they get to 28 inches.
http://animal-world.com/encyclo/fresh/characins/RedTailBarracuda.php red tail barracuda , getting 11 inches and says 50 gallons min.
