great point. I always make sure to check temp. before adding water. I'm just wondering if your loaches were the first to show signs of ich. Had similar experience, lost all my 5" loaches this to ich, all 5 of them.orlok said:When you do your water changes (especially large ones) make sure the new water going in is the same temperature as the old water in the tank.
I use a common aquarium thermometer when I use my python or buckets for just this reason.
A sudden change in water temperature is usually the cause. Especially a sudden drop in temperature. It compromises the fish's immune system. So make sure you have a reliable heater.
Oh yeah...
