ok so il wash my filter floss in tank water and keep tank cleaning every friday but now what couldve killed the aro i have seen ammonia poisoning and the aro had no sighns of that he looked like he lost control of his gas bladder

 

[rhodes_96]

if not from the supermarkets, then where do you buy the shrimps from in Aus? in the US, that's where we get them from, at least i do.

OP, sorry for the off-the-topic note above. hope your jar doing better...

1 Purchase shrimps from local fish store which supplies fresh seafood from around the country and imported fish.
2 Purchase shrimps from fish market (every capital city in australia has one of these.)
3 Purchase from supermarkets. Our larger supermarkets have fresh local seafood.

You've seen ammonia poisoning of fish, yet you think the ammonia in your tank played no part in the death of your jar?

 

[rhodes_96]

Have to agree with G shock, the presence of ammonia in your tank combined with the stress of moving tanks and an already stressed sick fish from a tank with not so good water to a smaller tank with uncycled water is definately what has caused it's death.

Two most of the most important factors when looking after australian / asian arowanas.

1 KEEP WATER QUALITY PARAMETERS 100% ALL THE TIME
2 KEEP THE WATER TEMPERTAURE AS STABLE AS POSSIBLE


This means NO ammonia, NO nitrite, and as little as possible nitrate (keep it under 20ppm). Try to keep ph between 6.5-7.5 if your ph is stable a little above or below this value it doesn't matter.
You should never have to wash your bio media as that should already be pre filtered by your mechanical filtration. If your Bio media is excessively dirty, then your mechanical filtration is not up to the task.
If you can during water change pre condition and heat the change water before adding to the tank. Try not to change more than 30% tank water in a single water change. Never skip the cycling process of a tank.
Hopefully you have learned a lesson for next time.

Have a good read on this forum, plenty of info to set you in the right direction.

good luck.

From the fish market

well my jardini died at 5:41 am
my 250g tank had been established 2 years before at my store, the jardini had been introduced about 6 months prior to today. the water is 80 degrees F, Ph 6.5ish, ammonia at .5 ppm, 0 nitrites, 15ish ppm of nitrates. i had never had any problems with the tank. His tank mates were a 15in red tailed catfish and a small African knife fish. the fish are fed with shrimp that have no additves, i never had a problem with those shrimp.

Yesterday at about 3:00pm i got to the store and saw the aro with his fins in the sand and mouth pointing up i though he was dead and when i tried to net him out he got back to normal, freaking out i decided to do a large water change thinking it might be the water so probably at about 8:00pm he was rolling and couldn't swim right, the current produced by the sump pump was knocking him around so i decided to switch him to a smaller 55g tank that had been used but the filter died so i put a new one in and changed half the water. while in that tank he got back to normal and stopped rolling at about 2:00 am he started rolling again and didn't regain control anymore and at 5:41am he finally died.

so what could have killed him?

You own a fish shop, yet you don't know the Nitrogen cycle, and seem to beleive it is OK to have Ammonia in your tank?!?

Please sell your shop.

Hard to say what exactly killed your arowana, you may never know. What you do know is that there are unhealthy conditions within you tank, those which you can fix.

maybe i missed it, but the OP said his family owns a shop where he keeps his fish, but he did not say it was a fish shop.

i knew it...that the culprit was not in the cooked shrimps, but didn't want to differ from what rhodes_96 had personally experienced btw, raw/frozen shrimps from the supermarkets are fine for arowanas, at least for mine.

it's a lesson learned i guess for the OP...
