Weather Loache...

[Steffyboy]

At the moment I've got 2 7inch weather loache in my 4ft tropical tank.
They're fantastic in there and are best mates with my huge African clawed albino frog but I've read in a few articles that having them in tropical conditions dramatically shortens their life span from 10 years to around 4.
I have a 3.4ft cold water tank with 4 smaller loache and was wondering does anyone know whether I'd be wiser putting them in my cold water for the long run?
They've been in there since they were babies and totally enjoy wizzing around and playing with the fish and love all the plants to hide in so not sure whether to swap?
My proper question is would it be ok to put them in a cold water tank after them starting off from a tropical?

If they've always been in tropical, its probably be better to just leave them where they are.
I do agree that weather loaches are normally coldwater/subtropical fish however they can be fine in tropical temperatures, it just speeds up their metabolism. 
If you were to put them in your coldwater tank, you may shock them and they may die from shock. I'll let other people be the judge of that though.

I don't really see how putting them in cold water would "shock" them as they would get used to that well acclimating. Then again, I'm not a weather loach expert so they could have low tolerance for things of that sort. The only thing I think of when I hear about a hillstream loach is airflow.

It may shock them abit being that they've now got used to warmer waters. If you believe that there fine in there I doubt it makes much of an issue keeping them in the tropical tank.

You need a very tight lid though for weather loaches as they believe they can fly sometimes. Worth keeping the lid on lockdown.

It could shock them because their blood temperature (around the same temp as the water) would be a lot colder than they are used to.
It would really depend on the difference of temperature between the two tanks and how well the weather loach was acclimated.
