80% is too much. maybe the weaker one suffered from shock. 40% (at the most) of conditioned water is enough.Sarcosuchus;730137; said:Since I have placed the Almond Leaf, the water really tanned and appeared to be thick. To prevent from any harm, I did about 80% water changing. I thought they would flee freaking out when I do the water changes but amazingly they were just calm, some even came close to me watching what I was doing lol, it was really funny to see that. Others were just naturally hiding. They were just calm and nice.
