I have a tank all set up I was going to get a bunch of caribe piranha but they never came through

I have 5 tanks all with piranhas so I’m looking to go a different route than the usual skittishness they have I am looking for an idea for the most aggressive fish I can fit in there. I like the outrageous aggression fish have

my Ideas are dovii, wolf fish, golden dorado or maybe even a group of different cichlids

mainly looking for an interactive fish that as soon as food hits the water it attacks
 
I'd say a 180 is a bit on the small side for the single fish you mentioned, and a group of cichlids in a 180 is gonna be a complete crap shoot.

The first fish I thought of when you said, "mainly looking for an interactive fish that as soon as food hits the water it attacks", is an Oscar!

One of the most interactive fish in the hobby, if not the most. And them gluttons will destroy every bit of food you put in there. They get big and a single specimen would fill a 180 nicely.

I agree Oscar’s are a good choice but here’s some more suggestions
Bartram's Bass (mini largemouth I think )
Arowana (always swims on top so gets food as soon as it’s hits water
Midas could be cool, they are like Oscar’s
flowerhorn ( Cool)
Sunfish ( they can be aggressive and get food really crazily)
These are my suggestions, tbh I think most will fit but idk

The biggest problem I see is tank size.
A 180 ( I have 2) is not really large enough for many fish you mention.
I would never subject a dovii to a long term cramped life in a 180, that's only a temporary grow out tank, and at best, too small for more than 1 individual dovii without any other fish. A 180 to them is a puddle
I have kept dovii in the past, and from 2 " juvies, a pair outgrew that size tank in barely over a year, and needed a minimum 300 gal tank.

Same for Dorado, in nature they migrate over 250 miles per season, a 180 to them, is also just barely a puddle.

The 180 community I have now, sees all kinds of action now when food hits the water.
It has about a dozen cichlids, and half dozen gobies, all only half size or less
It seems like it will be overly crowded soon, and need to be split up into a number more similar size tanks

The largest goby is about 10", and largest cichlid is only 7"

At max size, I expect the cichlids to hit 10".

Thank you for all the replies. Looks like I’ll have to redo some research on a smaller fish setup. Sucks because 180 is the biggest I can fit through my doorway these older hours we are built for midgets
 
What about a shoal of exodons? They aren’t a big monster, but are great mini piranhas.
There are some smaller wolf fish that can work for a 180, curu (black wolf) comes to mind.

Funny you say that I had a shoal of 60 exodons and they were great but I sold them to make the tank of Geryi piranhas

that’s one of the fish I was thinking was the curupira

180 would be great for a pair of Midas. Lots of strains to choose from. Also a pair of feaste are great looking, and can work with dithers.
