Kio fush trouble

[m and m]

So my girlfreinds parents have roughly a 500g+ kio fish pond. Many are more then two feet long and amazingly colored but it looks like the pond has taken a turn for the worse two fish died and one is swimming sll slanty. The other thing there isnt much motion from them other then the breathign any ideas whats wrong?

Warmer weather may have increased temperature and decreased oxygen levels in the water. Any kind of filtration on the pond system? Aeration? There are a LOT of variables here and more information will probably be necessary.

 

[m and m]

There seems two be roughly two filters on it, two waterfalls and several jets that push water. This pond has been there for roughly 6 year with zero probs this is the first time this has happened, It has been terrably hot these past few days.,

Good link, 650. Water temp may be an issue, as you said. Is it possible that some sort of contaminant got in?
