no it does not look like that. There are still the same amout of spots on the fishas there were last night. They have not grown in size either. Yes i totally agree on having to know what i am dealing with before treatment, besides nothing is open today so i am euchared anyway. Now today is water change day so what do you think would be a good amount to take out normally it is roughly 40%. I think this amout should still be fine unless there is a specific reason for not doing this please let me know.
