Yesterday I needed some plants to block the aquarium light so I want to Big Als and they said all they had were these Little things that float at the top in almost all freshwater aquariums there and they look like 3 leaved clovers ( about a couple mm long). The guy gave them to me free because they have so much and they populate fast. So I put some in my tank. It covered all the water at the top of the tank and it was darker so I was happy. They today I went to check on them and they were eating some of them? Is this ok? Could they die? My pregnant platy really liked it!
Is this ok?
