I saw some ivy, the kind that you see growing in most office environments most everywhere, growing in a clear glass vase of water at a friends house the other day. I was wondering would these make good aquarium plants just floating on the surface? Would they provide the same kind of ammonia "filtering" that the other "real" aquatic plants provide? They do grow in just water with no soil substrate. Would they be harmful to the fish? Any ideas?
