So today I decided to add some duckweed from another tank into my 10g ADF tank. Anyways, I come back a few hours later and find one of my females floating near the surface, popcorning down the duckweed! She was literally just floating and whenever a piece would pass her she would suck it up. I took the duckweed out because I didn't want her to overeat, but I'm kinda worried about how much she DID eat. Should I just not feed for a little while, or should I be worried?
