Arowana and its tank mates unable to digest fish bone?

[Nevin]

Normally I feed my main tank with Batu or Kunning chunk, the live stacks in the main tank includes Arowana, Peacobass & Northern Thailand tiger.







All live stocks that consume Batu or Kunning chunk are size 10 inches and above, they can sallow the fish chunk without any difficulty.

Recently saw a thread from Bro gtohow about the sudden death of Arowana:
http://www.arofanatics.com/forums/sh...d.php?t=534870

And this thread makes me have a concern about what I have practice for long time.

In fact, I frequently found undigested fish born at the filtration compartment, these bone should be came from the Batu/Kunning chunk that I fed.

Therefore would like to hear more inputs from hobbyist about this topic, or shall we de-bone the fish before we feed our pet fish in tank?

Thanks in advance

in the wild, the fishes got no one to debone for them.
they eat whatever fits in their mouth.

Yes, absolutely agreed.

But my concern is in the wild, Aro or other fresh water predators consume fresh water prey that able to feed into their mouth.

The bone hardness between small fresh water feeders/shrimp is different from the salt water fish like Batu/Kunning that we are feeding our tank fish.

So this is the thought I came across

the one in the photo is not kunning. It's bone is much harder compare to kunning and tamban ... my last post of suspect is this one..
I bought it as mistaken it as kunning..

hi bro

i am no expert but fishes in the world somehow evolved differently for survival, vs the domestically kept ones. Moreover we have no visibility on their mortality rate based on similar incidents

If it is not too much effort to filet, i'll just spend that extra few minutes to do so. Especially when your fishes are prized

my 2 cents

You are right bro, the pic I attached is not Kunning, it is Batu though they are look alike.

However, I find both Kunning and Batu spine bone are very hard in nature, and often I found un-digested left over spine in my filter compartment, therefore I am staring this thread to discuss.

Seems like a valid concern seeing as Wild Aro probably do not swallow fishes (as pictured) of that size I think. Might be a good idea to remove the main spine if you have that worry.

My aros likes to swallow the kuning head whole .... have been feeding this way for pond aros for 3 years, so far no problem

Looks more like a chunk of meat stuck in the filter compartment and left to rot to the bone..

If your fish poo out this size of hard bone.. I guess the anus tear already if not also lau sai all the way..

I think they should have no problem digesting ? Even frogs bones are digested.
Maybe if by some bad luck the bone accidentally pierces the stomach?
