Arowana fry disease?

[jdvue]

Hi,
I recently got a new arowana fry, it did not have the eggsac attatched when i got it. But now after 2weeks- the fry seems to have developed some sort of sickness-
I need some help diagnosing it below are sypmtoms:

-easily startled
-fin damage (slightly)
-some white fungus looking thing inside the gill
-a "D" shaped clear thing coming from the inside of the fish's gill
-reddening of the body
_______________________________________
the fry is eatiing normally.
i have added aquarium salt,
done water changes,
added pimafix
and raised the water temp.
_______________________
please give me any useful advice tips or ideas as to how to treat this...

wait... what u describe is actually very serious... White thing inside gill???

It could be Lernaea or Argulus, but are very very bad parasite....

Here's a link to check what you can identify and see what you have.. Also a picture of your Arowana would help... otherwise theres no way anyone on the forum can tell what it is....

Is you tank new? What are the ammonia and nitrite levels in the tank?

well, last time i checked it was on the high end, so i did a 50% change and boosted the temp to 80F.

Ive been treating it with pimafix for 3days so far, with little effect.

Im debating whether or not to try malachite green.

-and yes, there seems to be some sort or "white" string flowing loosly inside one gill, while both gills have a clear oval shaped flap sticking out of them.

Im debating whether or not to manually remove these things with tweezers

Before adding any meds your water parameters need to be in check. Good chance that the aros gill issues are being caused by the ammonia. You need to get ammonia and nitrite levels down below .25ppm.

the levels were about 1-2 last time i checked, so i did a 50%change, im not sure what it is now, but ill do a 30%change tomorrow.

the sickness still continued after i tried adding salt, raising the temp and performing water changes.

i didnt want to resort to meds, but after taking those steps above, there was no improvement.

You never did enough WC to reduce the ammonia to safe levels. If your ammonia is 1-2ppm and you do a 50% WC then your ammonia would still be .5-1ppm and unsafe. Why is tour ammonia elevated, is your tank cycled?

oh okay, well ive had my water cycled a while ago (like 3months) and i had my pleco and bichir in the tank, but now moved out the bichir and added the arowana. So the water should be pretty stable.

I think it raised higher ammonia happened when i added the aro which eats a lot more. (more waste)

I tried to counter this with more water changes, but still...

but ill keep a closer look on the ammonia levels. perhaps the ammonia levels have caused some sort of infection in the gills. i know that reddness of the body is a sign of bacterial infection, but i need to figure out the cause.

Ammonia poisoning is one of the biggest killers of aquarium fish. It occurs most often when a tank is newly set up. However, it can also occur in an established tank when too many new fish have been added at one time, when the filter fails due to power or mechanical failure, or if bacterial colonies die off due to the use of medications or sudden change in water conditions.
Symptoms:

Fish gasp for breath at the water surface
Purple or red gills
Fish is lethargic
Loss of appetite
Fish lays at the bottom of the tank
Red streaking on the fins or body


Ammonia poisoning can happen suddenly, or over a period of days. Initially the fish may be seen gasping at the surface for air. The gills will begin to turn red or lilac in color, and may appear to be bleeding. The fish will being to lose its appetite and become increasingly lethargic. In some cases fish may be observed laying at the bottom of the tank with clamped fins.
As the damage from the ammonia poisoning continues, the tissues will be damaged as evidenced by red streaks or bloody patches that appear on the body and fins. Internal damage is occurring to the brain, organs, and central nervous system. The fish begins to hemorrhage internally and externally, and eventually dies.

ok, so one aspect is solved, thanks! ammonia seems to be the likely cause of the redness...

but my aro is eating like normal, and swimming like normal still, but i cant overlook the ammonia. OK

do you happen to have any idea about the gill problem?
