Strange how everyone's experiences are different. I can't grow moss or swords in the Tang tank. Vallisneria occurs in the lake, though generally not where most of our fish come from.
I agree. Several years agoI was buying fish from a breeder and I was just trying to get java moss to grow for me and it wasn't doing well, and he was telling me he had been trying for years to get rid of it. He said he would clean his tanks and think it was all gone only to find it creeping up here and there again several weeks later, just a constant struggle for him. He didn't like it because it was always getting in his filters and clogging them.
