Monsters for my 55

[619aquaponics]

No. They average at about 23-25" full grown. There may be some needle fish that you could put in a 55g.

That's what I figured

You can try a few Florida Gars, Black Ghost Knife Fish, Elephant Nose, Fire Eel, Wolf Fish, Depending where you live and how much you are willing to spend, maybe even a few smaller Piranhas.

Never take advice from someone who has an ALLIGATOR GAR in a 30 gallon...

They do fine in freshwater, but they will outgrow a 55.

Do you want something that's fairly active, or are you fine with something that is more sedentary? Do you want something more colorful, or more drab? Something that is very owner-responsive? Help us narrow it down a bit...

Just a few I would consider....
Red wolf fish
smaller species of puffer
Green sunfish

I'm mostly in to natives, and there are quite a few that would fit what your looking for, it kinda depends on what's available to you locally though.
