Soooooo I bought duckweed, anubias, and some kind of tall thin grass. They are great, but there are these little critters in there that are like those water spiders but tiny. they are clearish-tan w/ six legs (I think, they are so small its hard to see).
1. What the heck are theses things, will they hurt my fish, and how do I get rid of them without killing the plants themselves?
2. The plants were in with other fish because it was from a LFS. The tanks there could be cleaner but the plants just came in today and I figured they would probably be okay since they hadn't been there that long. How long and how should you quarantine plants?? How will I know that they are safe to put in my tanks to prevent spreading anything from the fish at the store? Is there a way to sterilize them?
