help please
 

hi guys when i woke up this morning one of my green tiger barbs looks as though its one side is paralysed. He can only turn one way, its almost as if his caudal penducle is frozen. We have had a heat wave today usually being cold i keep my barbs at 26c but today the temp has been 36c outside so obviously my tank has been warmer. He is still shoaling but having obvious difficulty.
So i carried on and done my regular water change and about three hours later another one of my green tigers has started gsping at the top. im totally confused any ideas guys???

BTW all water parameters are fine, no different to what they have been

The warmer the water, the less oxygen in the tank. Do you have any type of airstone or live plants in the tank to help when it's too warm?

Sorry, I can't tell by your aquarium list which tank you're talking about.

sorry need to update my tanks. Yh the oxygen level is fine i always test it

Perhaps it's been doing battle?
