Hi guys, I’ve bought some Xmas moss on eBay and noticed couple tiny creatures, didn’t pay too much attention, manually removed them and left the moss to grow in a separate container. 2 weeks later I decided to plant the moss in my fish tank, I’ve checked again every inch for dead branches etc and put it in the tank. A week later I noticed a group of these guys on my moss (see pics). What are they? Should I be worried? I don’t have any fish yet. Besides moss a have riccia, anubias and baby tears.
