Top dwelling predators

That would work, as would chalceus, but like kno4te said, compatibility is largely based on if the jags will let it live long. Maybe a red tail cuda if you can get one (though I may worry about the jags with that).

I personally think that a school of dithers has better success than trying another large fish.

Red tail barracuda is something that I’d love to have in my tank for sure. But yeah I get your point. I’m going to get something that has a good chance of survival and I hope to get the answer here

My jag’s territory went from the substrate and all the way up to the waterline, it didn’t matter if was a top swimmer, if it still crossed the invincible border then it was given a vicious reminder not to cross it again, even in an 8 foot tank.

I’ve seen jags get along with other fish even in small tanks though, never knew that they could get so aggressive. My male jag is a wuss I feel but the female is a badass. She has even given the SH beating once.

Once eggs are laid, that male will no longer be a wuss.

I guess adding another fish would be a bad idea then. The female already attacks my hand while syphoning the tank, can imagine what will happen to my hand when they’re full grown and spawning

My jag wasn't aggressive, it was just territorial. An aggressive jag wouldn't even give other fish boundaries, it would just swim up and give the other fish a beating.

I had a group of 5" yellow jacket cichlids in a 140g I believe it was a 150cm/5' long tank ,got them when they were 2".The tank was crammed with hiding places if a pair were to form and start killing of the rest.I was away for 3 days and when I came back it was pure carnage - they had literally snapped their siblings in half and were herding fry around their tank as if nothing happened lol.

What’s amazing is that doviis still make all other parachromis look peaceful.

I know this is cruel but is there any way that I could stop the jags from spawning without separating them?

The only fish that can survive beating is a gar I feel because of their rock solid exterior

That’s really the only safe way. Anything else risks the pair rejecting each other and one potentially killing the other.
