Could I keep a pike with an Arowana???

  • We are currently upgrading MFK. thanks! -neo
I keep my Semifasciata female with smallish asssorted Ashricans and she never ate any. But the male is mercyless. Peanut's right. And it even depends on the temperature. Yesterday I disconnected the heater and the tank went a lot quiter.

Lowering the temp. does work, just gotta make sure you don't let it drop to much. 75 degrees is about as low as you want it to go, any lower than that and you could start having problems. Don't count on it to completely remove the aggression though, can't change that....its a core part of the fish.
 
I mostly keep pikes of a given species by themselves. I have seen it helpful to use some sort of dither fish to help with aggression among a group of sub-adult pikes being raised for pairing purposes. Other than that, adult pikes are best kept with their own kind to avoid damage to other tank mates, just my opinion. I do agree with the statement that different fish do have different temperaments, but you never know when that "peaceful" pike, that is fully capable of damaging (not necessarily eating) another fish, will do so.

I'm raising a goup of Cinta together and the agression that they show each other at times is amazingly rough, downright nasty actually. I don't know too many other fish that could take the abuse for an extended period of time. One of the most agressive species observed was a dwarf species I kept around 6 years ago. The fish weren't more than 5 inches long but they tolerated no other tankmates in a 6 foot tank.
 
^^^ well said!

Welcome to the site!! Glad to have another Crenicichlaholic aboard!!

Nice!! Solidly stated! Thats the way I keep most of my pikes also, although I have had success with keeping them with several different types of cichlids. if you are trying to keep them with other fish, and not having them as pairs (personally I think pikes look awesome when they are kept in pairs, so I always shoot for that) you should take into consideration the information on that particular cichlids aggression. A Crenicichla cincta is gonna be more aggressive than a Crenicichla acutirostris and so on. You wouldn't want to keep Geophagus with cincta whereas with acuts. you can to a certain extent. Key thing is start them all together YOUNG. Adding new tankmates to an established tank with Crenicichla in it is risky at best. 80% of the time the new fish gets harassed and creamed to the point of death. Along that point, if your pike is pickin on a certain fish, chances are that its not gonna stop and you'll have to either remove one of the fish and get a new tankmate, if any, or remove a dead fish eventually.

Crenicichla cincta is a pretty nasty pike, top that off with their max size they certainly are a challenge to keep. I used to have to keep my Crenicichla sp. 'xingu I' pair solo, they would attempt to kill anything in the tank with them. Having places that only the female could get to saved her several times too...so just cuz they are a pair doesn't mean the aggression towards each other is gone completely...:(. Congrats on the cincta though! What phase did you get? Green? blue? Red? The blues and the reds are my fav. but the greens are just as pimp.

That dwarf was probably Crenicichla notophthalmus, which is one of the most aggressive dwarfs out there...haha. I've know of people that have tried keepin them in a community tank with horrible results...:(.
 
The Cintas are green, good amount of orange on the tails though. The dwarf was actually Crenicichla sp. VENEZUELA dwarf (page 44 in Aqualog Southamerican Cichlids I). Picked them up at the '99 ACA convention. Also picked up some Labrina and Regani that trip. That was some time and a house ago. About 3 years ago I set up a new fish room after almost 2 years out of the hobby. Job pretty much prevented it - but the fish keeping disease is back.

Thanks for the nice welcome, excellent forum.
 
i have 2 black arows with 2 pikes, a xinguII ang a regani, they get along fine.... no problems at all:character0004:
