White Dots Cover My Cardinal

[dingweding]

I notice my cardinal tetra covered with white dots. At first i thought it will go away itself. But i notice they died one by one, although they still quite active and eating well, but every night i will find one struggle to death.

I increase the tank tempreature to 31 C today, and change part of water. Any other suggestions?


Many thanks

does it look like white spot? something like you dropped them in salt

It may well be whitespot, if it is then you should definitely go out and get some whitespot treatment.

Whitespot is sometimes brought on by bad water quality so it's definitely worth checking your water stats just incase.

Yes, it is white spot. My tank is quite healthy, i guess it come from other new fish. I remember if you increase the tempreature, it will be cured , am i right?
