Thanks all for useful info'. The issue with me here is that I am trying to keep two planted tanks with limited resources. Ford, Cambodia's temperature varies from 77 to 95 degree Fahrenheit. I am not really sure both Java fern and Anubias can withstand such such varying temperature especially during this hot rainy season. With light on the height side in my 29G tank, Java fern is not thriving at all. After I move it to 65G one, it quickly develops many green spots on its rhizome. I never use thermometer in both tank.
