KOIs and Silver Arowanas: Good Mix or Bad?

  • We are currently upgrading MFK. thanks! -neo
thought this was pretty well known, but you see the mix every once and awhile.

So which fish are going to suffer and be kept outside of their temp range?

Keep in mind koi are quite commonly bred in warmer areas of the globe, Malaysia for instance...

my advise from my own experiance, is seperate them asap. I put an arowana in my pond and they kept on following it around and it eventually died.

What?! Let me clarify what you said: kois followed your silver arowana around which led to it dying?! Would you be so kind as to expound on this... :confused:
 
I can see koi, especially during the spring breeding season, following an aro, nipping fins and stressing it to death...

hey good point! Hopefully the koi he purchased are from said warmer climates then.
 
Malaysian koi have no problems at temps of 76-78...I still wouldn't keep 'em with aros though...

try it for a week and see of arowanas adjust. if not get rid of the kois and add p.bass

I think this is good advice, funny though how smoothly you threw in your suggestion for stocking of I'm sure your favorite breed. :)

Actually I observed last night and noticed that the aros are not as skittish anymore. I'm thinking they are slowing getting used to the kids.

But I never realized Kois were so ROWDY. It's such a stark contrast to the majestic, serene and regal aros swimming in the most relaxed manner possible. The two IDs I'd have to say are quite relaxed as well. The Giant Gourami, stays virtually in her 1' round around the DW and hardly swims anywhere else, so apart from the Kois, everybody is relaxed.

Never realized 4 additional fish can pester virtually everyone in the tank. The aros are just plain irritated I guess, this might not be all that bad as I haven't seen them go at each other since the kois came in. It's just that they swim around with this look constant frown and irritation like I threw in some 2 year old kids into their peaceful home :D

i don't think it is a problem for Koi in terms of temp per se since i saw plenty of koi ponds over here and other tropical neighbor countries such as Singapore (eternally hot climate unlike Laos where it can get nippy in winter)

heheheh in terms of suffering from keeping outside of 'normal' temperature range ... i recon aro would suffer more
 
Update:

After 2-3 days, the aros mellowed down, the Kois hardly approached them anymore, of course one of the kois had a big scar on his face. I'm sure the aro gave it a piece of its mind, now it knows its place in the pond.

Currently they have been together 9 days and it seems like all is doing well. I noticed though that one of the kois had missing scales, I scooped it out and quarantied it, hope it didn't introduce any parasites to the pond:irked:

I didn't quarantine the kois :screwy:
