Hi

Just set up my tank last week. My KH = 6, PH = 7, dose 10 drops of iron daily, tank temp = 27 - 28.

From yesterday, I start to find dead fish ranging from cardinal, green neon, blue emperor, guppies. Some of them are without tail and torn fins. From my observation, some of the existing fishes have white spots on their body. Some fishes have torn fins or tail..

What is the problem?? This occurs only I have added in blue emperor 3 - 4 days ago....Is this possible to be fin rot or white spot? Or worse case both at the same time...How to solve this?? Need your urgent reply...

Thanks!!!!
