Cousin's 15FeetX10Feetx4Feet pond stocking overpopulated?

[Folklore]

The pond's dimensions are (LxWxH) 15x10x4.

He has this stocking idea consist of the ff.

6x Silver Arowana
6x Albino Red Pacu
1x Albino Clown knife fish
1x Albino Iridescent shark


2x Rtc
2x Tsn
1x Rtc and Tsn hybrid
1x Fly river turtle,also known as "Pig nose turtle"

20 fishes in total.

My question: Is it overstocked when all of those fish reach adulthood?

(Don't worry about the filtration,it is well taken care of.)

TIA

Shouldnt be a problem if the filteration can handle the bio load. That's one huge project !

Is it already built? I would probably do half that stock not all those.

 

[peewee]

that's a lot!

I would knock the # of aro's and especially pacus down a few, maybe do 4 ea. 4500 gals is a lot of water, but those pacus need like 400 ea.

 

[MN_Rebel]

Agreed, knock down few numbers of either aros or pacus.

Thx for all the feedback guys,i finally convinced my cousin to make the numbers of silver arowana into 1.We are pacu addicts so we still go for 6.

New stock list

1xSilver Arowana
1xAlbino clown knife fish
1xAlbino I.d shark
6xAlbino red pacu

2x RTC
2x TSN
1x RTC and TSN Hybrid

Total of 15 fishes.

 

[MN_Rebel]

I would knock off some numbers of the pacu.

If you want all six pacus, then consider cutting some of the catfish from the mix or maybe the clown knife and/or the iridescent shark.

 

[spadoc79]

drop half the pacus and 1 of each catfish
