The tank is a 180 litre and i used a glass thermometer until it smashed the other day when i was taking the temperature of the water for my change. Now i am using the stick on one but will buy another glass one tomorrow.

The water i use is 30c when i do my changes so that i dont get temp shock.

I know its really strange and maybe it is thermometer related, i never thought about that!

The fish that have white spot are, 1 discus, though improving, three clowns, four neons and a blue ram, all the rest of the fish are not showing sign.

Think my loaches are close to dying from it, and lost one blue ram, i have treated the water and have turned the temp up, its getting better but having to wait is horrible!
