View Full Version : Arowana "Exercise" Idea

01-26-2010, 02:34 PM
Hey I'm working on assembling a 125 for a new arrival, probably 5-6'' when he/she gets here. I just thought of an idea for when he gets bigger though, to avoid having to relocate him. What baout a powerhead that could cause a current down the tank, with enough power to make the aro swim against it, but not to big, so it can take a break if it wants to. I just thought this might avoid that condition where their gills turn backwards due to swimming in to small a space. I don't even now if that's possible, but the LFS owner said so aand he's never given bad advice yet. I DO have a larger tank that could be used to re-house the fish, but would like to be able to use it for another idea, but would love any opinions on this idea. I just thought of it yesterday.

I really don't think it will work.That fish needs to swim,not exercise on something like a tread mill.
Is there a leash to hold it in place to make it swim the current?lol
IMO Not a good plan.You need a larger tank for this fish!

I do have a larger tank NG, a 240g, sorry only mentioned it in passing before.

Thats a much better home!thumbs2:

Yea this ones just the grow out tank, but I was hoping it could be his home so the 240 could be used for MORE fish. Cuz who doesn't want that right?

I definately agree!
Have you room for more tanks?
Its the best way to have a large selection of majestic fish like arrowana!

I do have a 30, unused but maybe a quarantine tank in the future, a 55 with a cichlid "mix" (not really sure exact species, but my Orange zebras have spawned twice and the first batch are about 1.5''. Also, the 75 from the tank setup thread, the 125 above, and the 240, currently a "water storage system"

Arowanas do not care for current and your idea would probably stress it out bigtime. They come from fairly calm waters and are very graceful swimmers. When they get bigger (16+"), they won't mind a bit of current, but a powerhead pushing the water in his swimming space is not a good idea.

Ive seen wild arowanas in Venezuela and Guyana. It was always in calm, non turbulent blackwater rivers. No doubt, a little current will help the tank, but not one that is as powerful as described.

Maybe some sort of modified hamster wheel would work? :11:

yea maybe I'll try the wheel idea. Or maybe a ball so i can let it out of the tank once in a while. Thanx
