Happy holidays all,

I haven't been in the hobby long but one of the fish that attracted me to the hobby was arowana's.

Anyways, the lfs had a whole heap of juveniles (around 2 inches) of the saratoga - leichardti so i grabbed one.

Placed it into my 10 foot tank which has a bunch of cichlids which are now still only 2.5-3 inches (oscar, salvini JD's, and a larger maybe 4 inch vieja synspilum but he is not aggressive).

The day I put him in there he looked and swam exactly like i expected along the top of the tank, but next day, nowhere to be seen, and I did never find anything.

There is a lid covering the tank but I know he could have possibly threaded the eye of a needle to jump through a couple gaps but looked everywhere around the tank, outside & in but nothing.

Anyways next day, I put some juvenile blue acara into the same tank and within two hours one of them had their head taken off. Don't know which one did it but now I think this is what happened to the arowana as that was only about the size of this blue acara.

What do you think?

I would still like to get one but would have to grow it out some in a separate tank and introduce it later when its big enough not to be attacked.

Anyone else had this experience?
 
You didnt find anything? I would double check and close up all gaps no matter how small they are. Also if you do happen to get another one i would grow another one out till i was definetly sure its not big enough to be attacked. What other cichlids are in the tank and how big are they?

Doesn't surprise me if the cichlids killed the baby Arowana.
I always recommend growing them out first past 8 inches.
My experience with 3-4 inch Silver Arowana are that they are very fragile at that size. I would treat all Arowana species the same.

Oscar, salvini, couple jack dempseys, electric blue acara, vieja synspilum. Apart from the vieja which is about 4 inches, the rest are around 2.5.

Nope never found anything

Yes i think you are right. I made the mistake of thinking arowana in my head so they will be fine but its all relative.

I have another one now but managed to get hold of a 4 foot tank which I'll use as a grow out, along with the 3 remaining small blue acara which i also rescued from the bigger tank.

Here is a photo of the new one - all of 2 inches give or take. You can see why he was taken after looking at him. Seems obvious now I guess.

So now yes I'll leave it in this new tank until 8+ inches
