Got fish from the same shop as a friend last week and both now have whitespot.
I have Esha Exit but been reading and it says the treatment doesn’t work until the spots are present...only one fish has spots currently. So obviously I want to treat straight away but is it best to wait?
Also should I turn the temperature up? Some say it speeds up the life cycle of the disease? Do I want to do this? Tank is 25C, fish are two new platys, celestial pearl danios and emerald eyespot rasbora.
(As an aside I know about the GH issue and it will get fixed, I put the platys in there until I have two adult sized platys to add to the main tank with the male, didn’t want to add just one female initially as he’ll harass her too much).
Photo: blue fish has spots on tail and one fin underneath.
There’s also a possibility the sick fish is pregnant, can treatment affect this?
Unfortunately I can’t see a way to isolate the sick fish except in a 39l without a filter. Daily water changes would take the medicine out so would be pointless anyway. I do have a heater but my spare filter is in use.
It means spots need to be present on one/some fish. Don't wait for others to be infected, treat immediately. Do not raise the temperature; that is outdated advice and doesn't apply when using the correct medication.
