I have a 40 gallon tank and I just recently set it up a week ago I have a weird bacteria or fungus growing on it can anyone help me identify what it is and how I can prevent it from spreading also can it be harmful to my fish if I don’t react to it? Also if you have any general tips for aquascaping with live plants how to make them live and how often should I provide them substrate tabs and do I need to add Co2? I was thinking off adding shrimp to the tank but I am trying to make it a cichlid tank so how could I make it work??
