Will 2 silver arowanas live well with 1 Australian arowana?

After a few hours, when I noticed that the last silver acted a little weak, I moved it to a separate quarantine tank right away. It stayed at the bottom and started to tilt sideways. In the meantime, the Jardini, two parrots and the sweeper were fine in the 180. In the quarantine tank, I used the same water from the 180 and of course the same temperature. I added salt and methylene blue. It seemed to have recovered but then gradually it started to get weaker and weaker again... until finally it just stopped moving altogether.

I am so upset right now. I can't believe of the six fish I bought, I am left with three --two parrots and one Jardini. None of the silvers made it. This is one of the worst moments in my years of fishkeeping as a hobby. I am just so sad right now. If for some reason this Jardini dies, I'm going to sell everything and I'll never keep a fish again for the rest of my life. This just sucks big time.

Look to the bright side, bro. If you are still in the fish hobby, then save up and get another 3 silvers to comm again. Happy aro keeping.

Damn...thats a hell of a day. Sorry to hear the bad news bro. Did you manage to find out what was the cause of death?

At this point it's a mystery. The water I used was exactly the same as the 180 tank where four happy fish still reside with no problems whatsoever.

If you want to look at it from a superstitious point of view, I traded in my four kois (also believed to be good luck) to get the three arowana and one parrot fish. Maybe that's why the three silver died?

I am certain the water was good... cycled, clean, etc. I am certain the silvers weren't fighting. I am also sure they were 100% healthy. In fact they were very active. Another funny thing was that each fish died six hours away from each other. No joke. The first died when I got to work (8-9AM). That was the time I posted here I think asking for advice. Six hours later the second died (3-4PM). I posted here again around 2PM I think because my sister called me that it was "dying". When I got home approximately six hours after the second died, the third died (9-10PM). Also when I woke up this morning my 7-year old cichlid was dead. That's four fish total for the four kois I gave away...

I'm not superstitious at all. I love kois and arowanas over any species of fish not because they're good luck or anything.

Thanks for the condolences to all and for keeping things positive. I'm very much devastated by all this.

Hello,

I just purchased 2 Silver (3") and 2 Australian (3" and 4") just 3 days ago. Housed in a 100 gallon tank that used to be for my Kois (now in outside pond). They seem to be doing fine together. Although the larger Australian chases the smaller one around a bit, it does not seem to give the Silvers any problem. I noticed the Silvers stay really close to the top while the Australians cruises just below or around in the mid level of the tank.

I could be that I introduced them to their new tank at the same time so there was no time for anyone to become territorial. I've also read that they are less aggressive when there are more than a few aros in the same tank.

Mutiny, It sounds to me that death of your fish may be due to stress from moving if there are no signs of fighting. Sudden changes in water temp and condition may be enough to kill the young aros. Did you do a water change after you remove the kois? Was the water in your 20g tank conditioned? I think the kois can withstand a much worst water quality.

The guy I bought mine from told me to set temp to 80-86. What's your's?
Other thing he strongly emphasized was to remove all charcoal from the system.

i bought 3 silvers they all died withen two weeks not your water in tank bad arowana's make sure there thick and moving around ok the pet shop.they gave me one aro back because he died within warranty he was a bit bigger and very healthy looking eating very easy.two weeks to the day last of the first three dead.they would eat very little and moped around tank.they were probley stressed to much or just never recovered or were in shock.they looked bad when i put them in tank.so beware when buying,whatch for movement and thickness.getting ready to fed my healthy one,he was looking at me when i went by my tank.he loves redworms.about dead one's.about live one.
