Are there any rules for treating white spot in a planted tank? Usually I would use the 'Esha' copper based treatment (good stuff!) but this is the first time I've had white spot in a planted tank, so I don't know if that's the right thing to do? I also have kribensis fry (typical! They finally spawn and I get white spot) they are free swimming and came out with their parents for the first time today. They are slightly bigger than molly fry. I also have a clown loach, and humbug catfish, and coolie loaches so I'd be using a half dose of the Esha treatment. What shall I do?!?!?! It's not advanced white spot - I only noticed it today on my clown loach, and looking carefully some of the other fish have the odd spot aswell. It's not really bad though, I've caught it early. The tank is 100gals and running at 27 degrees C (the lights heat it up). This serves me right for not quarentining my new neons that I got a week ago. They looked so healthy, but obviously weren't.
