Using my old koi pond for 4 silver arowanas?

  • We are currently upgrading MFK. thanks! -neo
No aro in captivity that i know of has reached 3 feet.

Are you excluding those with tropical ponds like TLkmDN, and public displays like the Berlin aquarium which I regularly post pics of in threads like this? A 3' silver in a pond or public aquarium isn't an unusual sight IMO, and I can't help but feel it reflects badly on us as fishkeepers if our specimens in tanks don't get close to that size.

I'd be a bit concerned about the lack of depth when your silvers get big, but I guess you can try it and see.

What do you mean excluding? Sorry not good in english. Speaking of TLkmDN, i have just asked him about the pond walls and he said "the one foot wall is definitely a huge plus size and shud prevent small accidents from happening". If ever they 4 silvers grow too much for the pond. Il exchange the koi with them so the silvers would be in the main 2000 gallon pond

Excluding means "not counting" or "ignoring" sort of. Miguel said he didn't know of any aro in captivity over 3', and seems how TLkmDN has more than one over that size, as to many public aquariums, I asked if he was intentionally not including them in his comment.

When they are big enough you could probably keep the koi and the arowana in the 2000g pond together, but either way the big pond will be a better long-term home for four fish that potentially grow to over 3' long.
