bagarius yarelli lifespan?

[Stackdeck]

Any1 know the average lifespan of bagarius yarelli or any factors affecting lifespan

[Silurus]

The literature I have seen indicates that they live for about 8 years in the wild. YMMV.

[Redtailrob]

Only 8 years!!! That surprises me.
Usually such big Apex predators have a much longer lifespan.
They are very slow growing for such a short lifespan @ least in the captive environment.

[Stackdeck]

How about growth rate ?

[Redtailrob]

What in the wild or in Captivity?
Please be more specific.

Evidence suggests that Wild fish grow incredible fast, however my tank kept specimens are only 12 &14" respectively after around 15 months. Although I'm sure if i feed them more & more often i could achieve much faster growth rates.
These have the potential to be huge even in home aquaria.

I think it's in the wild

[Redtailrob]

Good point!!

Would love to know where that Info comes from?
Silurus can you enlighten us?

[Viktor Jarikov]

Hi Silurus,

If you don't remember where 8 years # came from, can you give us a point of reference? Say an RTC in the wild, would it still be expected to live for 20-30 years (I mean "ideal" wild conditions, no accidents, good stable health)? Taksan's two 4.5-footers lived for 27 years in his 15,000 gal pond.

Or vs. a TSN, S. glanis, etc.?

I only kept mine alive 12 years (1997 to 2009).

Slow growth and only reached 36".

Wallago leeri affect their lifespan.

[Viktor Jarikov]

Your leerii killed a 3' yarelli? He surely could not swallow it. Did he constantly try to bite pieces out of yarelli?

[arapaimag]

Both of my leerii attacked the goonch constantly. Yes biting it. My goonch only grew to 3 foot. My leerii are a lot bigger.

Leeri and yarrelli , my two fav cats. Sad ly leeri cannot co exist with anything.

Have you seen the videos from arapaimag - his leeri live with plenty of other fish - but he does have them in a BIG tank.

[Stackdeck]

Havent seen the vids , but i really woulndt risk leeri with any fish , unless i were to have something similar to arapaimags tank in the future . Although i do notice that attu is more docile , and ive been told this by several people in addition to my own exprerice.

[Stackdeck]

By the way arapaimag , do you think you could share how long it took for your yarrelli to get 3ft? diet and water parameters would be helpful , thx alot

[arapaimag]

Sorry for the delay.

Mine took about 6 years to get to 34-36" and then just stayed that size.

I currently feed the 2 big tanks on three days each week.

A combination of Martin's pellets on Sundays

A combination of fish (Mackerel, Herring, Salmon, Trout, Smelt) not all at once whatever I have in my freezers on a given day. This is fed on Tuesdays

A combination of Flakes from Wardley and Tetra on Thursdays.

Of course the large tank has many hundreds of breeding cichlids that provide exercise and food for any hungry fish. The Goonch most often hunted for it's food.

[Stackdeck]

Thats a long time , with a big tank and alot of food , thx for the info. Recently there are imports of large 30+" specimens in
singapore with a price tag of just under 1000sgd
