i went to pick up fishes today, and along with others i picked up a 2 inch silver arowana.

right now he is in QT -10 gallon for a few days. he was the only one left in the tank, so he must have been left behind for a reason. after looking at him for awhile, he is very skinny.

right now he is eatting by hand blood worms.

i heard that when they are young they are VERY delicate.

how many feedings per day should he get to fatten him up fast so he is less in the risk zone.

he is also very confused, as i do have some feeder rosy in their with him, and he schools with them, often leading the pack.

jardini gorwth, my jaradini # 1 has been here for 4-5 months and really hasn't grown any, still around 5 inches and eats 2 times aday only blood worms.
he lives in a 75g by himself.

my silver # 1 has been here for the same time and started at 4 inches and now is around 6 inches.
he is in a 75 g with cichlids. he is fed once a day, blood worms and color bits.

if arowanas have a fast growth rate in their first year, why is my jaradini a shrimp?

Yes, when Arowana are that small they are indeed quite delicate. If you don't currently see a yolk sac, it must have absorbed it within the last month, perhaps even week. In fact, 2" is even scrawnier than normal; your average baby arowana straight out daddy's mouth usually has another half inch or so on them unless my memory tricks me.

Try not to have motions that are too quick in front of the baby arowana's tank. Especially at this age, they have pretty high blood pressure, or so I'm told. They're pretty easy to send into shock (which will give you just about the same heart attack to you) since the arowana will just go stiff and stop swimming altogether. It's not the most comforting thing for an arowana owner to see, that's for sure.

As for the Jardini growing slowly, it might be because of the restricted diet. Bloodworms alone isn't going to contain all the essential nutrients, and as the jardini and the silver live halfway across the planet it's probable that their nutrient requirements are a tad different. In any case, a variety of foods could help. On the other hand, the Jardini could just be a slow-growing species compared to the Silver.

The aquarist is one who must learn the ways of the biologist, the chemist, and the veterinarian.

i tried adding to the diet, however he wont take anything else. just figured him to be spoiled.

alright, so how long do you think it will take to get him into super form. my larger silver i got when he was big enough to fend for himself, so i am very new to this.

my newest jaradini # 2 i also got today, he is around 5.5 inches. i do have him in a 55 gallon as i was told that never mix arowanas. i do have plans on moving him to a 125 o a 75. unfort i was unscessful in getting him to eat on anything.

i am hoping that is b/c of the stress of the move.
