I have just got my first tropical aquarium. I have had it for almost 3 weeks, but I have not added fish yet. It is a 120 litre tank, which has gravel in it. There are currently 5 live plants in there. In the passed 10-14 days there is some (what looks like) white, thin cotton woolly funghi looking stuff that is currently sitting on the gravel. It is quite long and is swaying with the filter. I was wondering if any one knew what this might be - and if I need to do anything about it. I have not touched it yet as I was hoping it was part of the cycle of the tank.
I was also wondering if anybody could recommend any tropical fish ?
Any help would be gratefully received please
