Indoor water feature pumps
Aquariums have been a popular way to introduce the aquatic world into our homes for a very long time (probably over 2000 years as indoor fish keeping and aquatic plant displays were popular with the ancient Chinese), but there are other ways to bring the aquatic outside inside.
Consider an indoor pond or water feature. These can be pre-bought or homemade and can accommodate outdoor pond or bog plants that would usually be outside. Choose smaller varieties such as miniature Bull Rush (Typha Minima) and Japanese Iris (Iris Kaempferi), there are many others.
You might want to introduce a small fountain spray or bubble water over rocks or pebbles and to do this you will need an indoor pump or pump kit.
