Are jack dempsey cichlids aggressive?

[5x5]

If put together at a early age can you have a jack dempsey with a red devil?

The early age will not matter by itself. Most cichlids get meaner as they mature.

I've never owned a red devil, but other members on here have had some real psychos. Your success will depend on the tank size and a little bit of luck with your actual specimen.

What size tank are you working with?

It's hard to notice in a picture but in this one he is puffing up at his reflection so fun to watch lol.

Yep, It's called "flaring" in the fish world.

Isn't that gill flaring?

 

[Plecos4596]

Sorry so many questions

They flare both the fins and the gills. The gill flare is essentially them biting down (like a human baring their teeth).

sorry, not the fish of topic, but the firemouth flares big time =) his whole little red throat stuff comes out. Unfortunately, it doesn't seem to scare my nasty little jewel...

I have a male JD and he is aggressive. He rules the tank over my male Green Terror. Only really beat the GT up once though. He will chase it every day but there has been no fighting since the GT got its *** kicked.

Oh yeah they can def be aggressive

 

[Plecos4596]

But they can hold their own against some bad fish to I'm guessing?

 

[Plecos4596]

Oh by the way can anybody sex my JD?

I wouldn't count on that.

Oh oky doky thought they had the name jack dempsey for a reason.

JD's are very aggressive. They can be kept with other cichilids BUT you have to watch them and IF fighting occurs remove one. Personally, I'd only keep JD's with JD's or a Red Devil.

Very Aggressive? Compared to what, a platy or a molly? They are not pushovers, but calling them very aggressive makes me think you haven't exactly been around the block when it comes to SA/CA.
