The duckweed I ordered from Aquabid came in the mail today
I bleached it to sterilize, and I half expected it to turn white (someone? posted a video over the summer of duckweed they had bleached that turned white/yellow), but it didn't It is currently in a 2 gallon container. I am going to go look for a longer shallow container to keep it in this weekend, and this summer I plan to put it in a big tub outside to grow (with mosquito netting over the top so that it doesn't turn into a larvae pool).
It reportedly came from a 'fish free' aquarium (part of the reason I bought from this seller), but it came with some ride alongs nonetheless. I am curious if anyone can identify them? They look like maybe they are some type of shrimp? The bleach did not kill them so I spent a half hour transferring the duckweed from one clean bucket of water to the next until I got rid of all the ones I could see.
I am super paranoid about bringing anything nasty into my aquarium from this stuff, so I think I will just let it sit for a couple weeks before I try feeding it to the fish. Hopefully the bleach was enough to take care of anything, but the fact that it came with things swimming around in the water freaks me out a bit.
