Hi
Help needed here please.
45ltr biorb which is relatively established. A few tetras, mollies etc.
In the last few days I have noticed the growth in the pictures appear in various places on the tank sides and rocks. Each appears to be growing.
Any idea what this is and do I need to be treating it ?
