So, I’ve not put anything in my 90l shrimp tank for months. And today I was looking in there and saw about 5 single bits of duckweed! And as we all know that will soon be a lot more! But how did it get there? If it had somehow got in last time I added something 3 months ago then there would be a ton of it by now?
Very curious!
