Hello, I have recently added plants to my 5 Gallon cycled betta tank and the Anubias has developed these small brown spots on the leaves. What could be the cause of this?I currently don't have any co2 in there but I am adding seachem flourish and will soon start adding Seachem Excel once it arrives in the mail. Also I have the Anubias planted in gravel and the water temperature is 77 farenhite. Could the light be the issue? I am using a 10 watt 10.5 inch clip on light which I bought on Amazon >>> If I am doing something wrong or should start doing something please let me know would love to hear any tips.
