Ideas for most aggressive fish for a 180

[Joshuakahan]

You should try eyebiter ciclids. They are extremely aggressive. They literally bite other fish's eyes.

That’s somewhat of a myth, but I wouldn’t use a 180 on a single hap, I’d go full rift tank, maybe a predator hap setup if I was to go this route

For a 180 I would suggest a jag cichlid. If raised from small you might be able to get a pair out of them if you purchase a group.
Ultimately you will end up with a pair or just one. Very personable fish and I think they look nice.

Imo long term, jags get too big. World record is 28" so bear that potential in mind when getting one.

And my favorite video of haitiensis:

All of these hit within the 12-18" range. They are all fast, visually pleasing, and aggressive feeders.

That robustus is sweet! Never seen those

Only african I can think of would be a buttikoferi. Aggressive to other fish, but mine were not very interactive with me.

I like the pattern more on female jags.

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

I agree with a fahaka puffer. Ive only kept smaller puffer species but they are very interactive fish and I would love to have a bigger one myself but no tank to dedicate to one. Look up some puffer feeding videos , you cant help but be impressed with them as a predator.

Here’s a fahaka I had a few years ago, I ended up selling her but she was awesome
