eek that's a possibility. We are surrounded by farmground so I guess it's possible that the farmer sprays insecticide. I do know he sprays herbicide. I'll make something to hopefully keep them out of the tank. They've never been a problem in my 20g, I guess because there isn't a lot of light in that room.tekknocolor said:I don't think that it will affect your fish, unless there is some sort of insecticide or something similar that was sprayed on the bugs. Here's some info on the bugs at the following link:
