Arowana - Cloudy eyes and tail rot/ tail biting

[deep3185]

Look at these images and can someone please help me.



In the beginning it was cloudy eyes and I had to isolate the infected fish which was spreading to the other Arowanas.



My water parameters are fine, changing 20 water every alternate day. Currently using Epson salt and 3rd Generation Yellow Powder from OF as advised.

If it is tail biting, a similar thread was recently made on this subject which you may find helpful: https://www.monsterfishkeepers.com/forums/threads/own-tail-biting.749641

Your tank looks very bare. I'm thinking adding decor and substrate just might be sufficient to provide enough enrichment to stop any tail biting (as mentioned in the link).

One last thing, what do you mean by your water being 'fine'? The reason I ask is because the commonly thought of as fine 10-40 mg/l NO3 is actually too high - it should be no more than 5 mg/l taking duanes ' advice, so if you have over 5 mg/l and consider it fine, it may not be.

I wish you the best of luck for this fish's recovery.

Did the other arowanas attack it?
I suggest doing water changes every day or atleast 50% every other day.

Something else you may find useful concerning the mentioned enrichment.
Enriched environment in aquaculture enhances the survival of fish from bacterial disease.

The same principle likely applies to the fins if this problem is enrichment related. More enrichment means less stress, less taxing on the immune system, and superior recovery strength.

My guess is it got attacked by the other Aros, then got stressed, then got fin/tail rot. If you are treating in hospital tank with "yellow powder" (antibiotics), along with salt, warm temp of 30 C, daily water changes - then it looks like it will pull through. You are obviously looking at many months to get the fins back. Provided the root of the fins and tail have not been damaged they should grow back. I'd be interested in an update in 2-3 months (assuming the fish lives).

Sad to let you all know that he died this afternoon. Hoping for my other Arowanas to survive this difficult times.

Sorry for your loss.
Exactly how many arrowana do you have and what tank are they in?
Just looking to avert any further issues.
