Oh! I used to have aquariums! But usually just with fish and artificial plants and decors. But from those few years I had them, I have used janitor fish to clean off all the algae in my tank..very hard working ones..but the unfortunate side, if they run out of algae to clean out..they will then "clean off" the fish, eventually accidentally killing them. And they get so huge too.
Another one that I know that can eat algae are amano shrimps...sadly, cannot find a pet store locally that sells them.
Now I do not have anymore aquariums..really a lot of work to maintain. But I do miss them a lot.
My husband wants me to try Wabi-Kusa..I still have to read more about it ..but it does look interesting.
