Hello All,
i've just register myself to post this thread and see if anyone can help me on this. I have a silver arowana with 40cm that started to have the fins broken and stopped eating.
For what i was able to understand this can be related with stress and it will be naturally solved, with the help of some salt 0,5% and increasing the temp.
Nevertheless i would like to ear your opinions on this, since is not only the arowana that is stressed :irked:

Here's a picture to better understand the problem (sorry for the quality).

Thanks,
Luis

I'm changing the water weekly (20%). 15 days ago i changed a little bit more (40%).
But water parameters are stable.
 
has its diet change? Are you feeding it feeder?

Have you change the water since the 40%? Aro are pretty tough fish.... but sometime it doesn't take much to get it stress....most of the form i've read and also from personal experience and also from people i know that own and have had aro die in most case is a week after water change they experience this kind of symptom.....

if you have a small tank to quarantine it do so with some added air stone. Use some filter drinking water and some of the existing water for the quarantine tank..... this is what i'm currently going through.... mine is doing much better with this method.....
 
Are you saying it is not the only arowana in the tank? Looks to me that it is getting beat on by something.
 
I don't know if he has other fish in there but i would think if his aro is already at this stage anything in the tank could hurt it. It's best to quarantine it for treatment to do a process of eliminating of what has cause his aro to be stress.
 
if push comes to shove, take it to the vet.
thats what i did. my 4" arowana developed this fin rot that NO OTC meds could get rid of.

vet. prescribed amikacin and baytril shots.

but, thats if it gets worse.
 
This is the only aro in he aquarium, I had also one jaguar chiclid that i've already remove it (however i never detected any kind of agressiviti between them).
Isn't this the same as this? Picture with the following legend "Rough looking fins like on this arowana normally heal in 2 to 3 weeks."

Isn't it the Fin membrane Tear that is identified in this page ?

The problem is that i can't find any pictures of other cases to compare with mine :((

The vet is not really a possibility, normally in PT they are not focus in aquariums.

Thanks,
Luis
