Ideas for most aggressive fish for a 180

  • We are currently upgrading MFK. thanks! -neo
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
For interactive, I’d

what about a fahaka? That will check all of your boxes. That might be the most aggressive and interactive fish I’ve ever had.

My favorite type of Pike are the Orange Pike Cichlids (Xingu 1). Look them up in the Pike section of this site and on the internet. They are beautiful and efficient predators.
 
Also like to add some species of Pike Cichlid are from low PH waters for example the Amazon and will be susceptible to HITH if placed in a high PH environment.
 
Here is a pair of haitiensus i had, and kept in a similar size, 6 ft tank.
Of course, at adult size, they would not tolerate any other tank mates.
The male easily hit @ 15", the female slightly smaller.

Their presence, and imposing and dominant personality made a 6 ft tank look tiny.

I second the haitiensis. My vote goes either haitiensis, parachromis friedrichsthalii (former loisellei) or multifasciatus (former friedrichsthalii), or m. festae. Could also do a female blue umbee if you're fine with the relative lack of color. If you want something more interesting, you can look into the bigger Malawi haps like champsochromis, tyrannochromis, nimbochromis and buccochromis. Serranochromis is also a cool option if you can find them. I don't really know anything else that fits the bill for "most aggressive" and fills out a 180, while being easily accessible. The smaller bass species are cool and all but that involves finding and catching an individual of that species at a legal size. No one really sells them. Sunfish don't come anywhere close to the aggression of cichlids. My p. multifasciatus (3" at the time) killed like 6 green sunfish (some bigger than him) that I was housing with him temporarily within a matter of 3 days. Pikes just kinda slink around, basically the same as getting a bichir but more colorful. You're not really getting a glass banger out of those. Amphilophus are cool and pretty aggressive, but not as crazy as the aforementioned species. Close second though.
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
Flowerhorns are a waste of money, you're paying for a fish that is guaranteed to get a disease and live a quarter of the amount of time it's purebred ancestors would. A 180 is too small for any arowana.
