The fish you have is a black, or what is known as a jardini in some areas. That species of fish get very large, so you guys have two choices, return him or get a bigger tank, I have done the research on housing any species of arowana, here is the link for where i am buying my aro tank,glasscages.com, these tanks are ALMOST ideal for housing aros, particulary silvers and blacks,go for the 240 gal long, or the 280gal. I will warn you the fish you guys have is NOT for the beginner aquarist, but with the help of the online community and the many books available you can keep it correctly. I highly advise you take rallysman's
advice and go to monsterfishkeepers.com's arowana forum though for more users who have had or currently have arows.

Thanks for coming to us for help, I knew someone who did the same thing, but didnt ask anyone about it, and they lost the fish, ME, i regret it every time I look at an arowana, but I learned what to do and what not to do

Jardinis and blacks are way different. Jars dont get nearly as large but have a much worse attitude.
 
Ok look, if the Arowana still had the egg sack attached, it did NOT eat the tetras and it especially did not eat the guppies, especially if theyr'e fancy guppies.

This kid is talking about a fish no more than a week or two old.. it's still feeding off of it's egg sack and will not eat any feeder fish.. even if it was big enough to eat a decent sized fancy guppy (which I highly doubt), it wouldn't happen until the egg sack is dried up and dropped off.

Dude, baby arrownas feed off feeder guppies and crickets..How do I know? I had one before!

Guess you have a crystal ball , and you know everything..Wow, you are one intelligent guy! Now you are saying that a baby arrowna with the sac attached would not go after small feeder guppies or worms? Wow, they must starve themselves to death!
 
Chill out my friend :)

I'm guessing if the egg sack is still attached then the fish would be getting all its sustainance from the yolk within it? Kind of like when a tadpole turns into a frog and reabsorbs its tail, it doesn't need much food because it gets sustainance from the tail. I think most fry, maybe with the exception of livebearers, go through a stage where they use their egg sack for food. So following this reasoning, the fish would not require or attempt to eat any other sort of food until the sack is gone.

Maybe someone more experienced can step in and clear this up? I'd really like to know.
 
Sorry the fish has died. It jumped out of the tank.

How is this, you stick with your statement that baby arrowanas starve themselves to death and dont eat anything while their sacs are still showing..Anyway, if you want to argue with this man who has a Phd and have raised baby arrowanas. In any case, you probably would still not understand anyway and you would say you are right and he and I are wrong. He writes in his website:

"In early 1991, we stocked an 8-foot-diameter aquaculture tank with 12 baby arowanas that measured 3 to 4 inches each; several still showed yolk sacs. The tank was equipped with flow-through freshwater and covered with nylon mesh. The latter is an important point.These fish will jump out of their tanks regardless of their age or size,so tanks should be covered at all times. The tank was stocked withmosquito fish, culled mollies and other live feeds on an average of twice a week."
