Hi all. We clean our tank once a week, and recently I noticed tiny silver larvae looking things swimming on the surface of the water. There doesn't seem to be many, and our little guy has been eating them whenever we put food near these... things. My boyfriend seems to think that it's just mosquito larvae and it won't hurt, but I'm worried that they're parasites of some sort. Does anybody know what I'm talking about? Are these tiny things harmful, and I should just take everything out and make sure they're all dead? When we clean the tank, we vacuum all but 1/4 inch of water.
Thanks in advance!
