Evil Father HELP!!!

Sorry to hear about the fish, may it rest in peace. Please try to persuade your dad not to buy another one. Read up on some of the articles on this site about cycling, then you could keep a small community tank with a small school of neon tetras that you like.

Watermelon: Mate, I'm not trying to pick a fight or anything.

I'm fully prepared to accept that I am wrong, as soon as someone comes along with evidence that baby arows eat live food while their egg sack is still attached and full. I'n not suggesting that they starve themselves, the egg sack is full of yolk, yolk is highly nutritious, lots of protein and iron i believe. I'm assuming that the yolk is steadily absorbed into the body, thus the fish needs no other food while still feeding on the egg sack.

several still showed yolk sacs.

I draw your attention to this particular section. The word several, to me, indicates that only one or two of the fish still had their egg sack. I would think that the ones without egg sacks would be eating the feeders, and once the other couple of arows depleted their egg sacks, they would start to eat the feeders too. So you see this does not prove that arows with egg sacks eat other food, thus there is no disagreement between me and this professional.

I'd appreciate any information anyone might have on this subject.

Sorry for the off-topic everyone. :)


EDIT: Whoops, you posted again while I was writing. :) hey man no hard feelings, we're all here to learn. Did you manage to find some other information? If so, please post a link or something, I'm quite interested in this area.
 
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.

maybe with the exception of livebearers

Even live bearers go through this stage :)

In my experience the yolk sac is transitional in its purpose. It provides a food source while the arowana becomes more capable of feeding itself. It uses both sources simultaneously in this iffy period immediately following birth. Evolution's extra little assist. I have definitely seen silver arowanas (Osteoglossum bicirrhosum I think) feeding while they still had their yolk sac.

Sorry the fish has died. It jumped out of the tank.
Sorry about your loss, but who could blame the fish? It probably thought your room would be bigger to swim around in but when he jumped out noticed it didn't contain much water....
 
I was going by what the LFS had when I said jardini and black were the same thing rallysman, Thanks for correcting me though:) , and they are most definitely jumpers, LFS here has gone through 6 covers in 2 years due to those guys, Ive mainly kept silvers, i ventured into cloudy waters once by keeping an african arowana, had to get rid of it, due to it was bullying my oscar, (i know, i was thinking it was going to be the other way), donated it to the J.L. Scott Marine Education Center, a college sponsored aquarium in Biloxi, MS
 
I will try my best to convince my dad to not get anymore arrowannas. I don't think he wants to anymore once I told him he needed a bigger tank. Thank you guys, now I can buy some fish, I hope.
