I bought some java moss today that is attached to a cork (so it can float). I bought it from a very nice LFS near my in-law's house. When I got home (5 hours later) and took it out of the bag, I noticed little bugs zooming around in the water. I assume they are on the plants, or possibly on the cork if it is decaying. I rinsed the java moss and cork in hot water and then put it in my tank.
Are these bugs ok? Is it common to have these on plants (I have never had live plants before). Or should I take it out of my tank and toss it?? I also bought water sprite but did not see anything it its bag. Can I leave that in my tank as well?
