12. 12. The underwater plant holder of any previous claim, wherein the first container and the second container are substantially longitudinal and have respective first and second lengths that are substantially equal.
13. 13. The underwater plant holder of claim 12, wherein the first container comprises a first open end and the second container comprises a second open end, and wherein the underwater plant holder further comprises a cover for covering the first open end and the second open end.
14. 14. The underwater plant holder of claim 13, wherein the cover comprises a third plurality of apertures.
15. 15. The underwater plant holder of claims 13 or 14, wherein the cover further comprises a wall extending from a perimeter of the cover.
16. 16. The underwater plant holder of claim 15, wherein the cover comprises a third container with a third open end.
17. 17. The underwater plant holder of claim 16, further comprising a cap to cover the third open end.
18. 18. The underwater plant holder of claim 17, wherein the cap comprises a fourth plurality of apertures.
19. 19. The underwater plant holder of any of claims 13 to 18, wherein the cover further comprises means for releasably attaching the cover to: the second container and/or the first container.
20. 20. The underwater plant holder of any previous claim, further comprising a base, wherein the base comprises: means for releasably attaching the first container to the base; and/or means for releasably attaching the second container to the base.

Description

TITLE UNDERWATER PLANT HOLDER TECHNOLOGICAL FIELD Examples of the disclosure relate to an underwater plant holder. Some relate to an underwater plant holder for use in aquariums and/or ponds. BACKGROUND Aquascaping conventional planted aquariums typically starts with a base layer of a nutrient rich substrate (such as soil, organic matter, compost, or fertilizers). A layer of gravel (or stones, sand, shingles, grit, or the like) is then typically placed on top of the base layer of nutrient rich substrate. Softscape components (for example, plants and/or other vegetation) and hardscape components (for example, rocks, pieces of wood, and/or plastic decorative pieces) are placed throughout the aquarium and/or pond. The layer of gravel, softscape, and hardscape components act as a medium/surface for beneficial bacteria (e.g., nitrifying bacteria, ammonia oxidizing bacteria, or nitrite oxidizing bacteria) to grow/colonize on. In the case of plants with roots, the roots extend down through the gravel layer and into the nutrient rich substrate in order for the plants to access the nutrients contained therein. Conventional planted aquariums and/or ponds are not always optimal. For example: • Removing/moving the plants in order to attend to the fish is time consuming (e.g., each plant must be removed one at a time). Removing/moving rooted plants causes leaking of the nutrient rich substrate intothe wider water volume (i.e., the water column) as the roots are pulled up/out of the nutrient rich layer, causing unwanted discoloration of the water and wastage of the nutrients comprised in the nutrient rich substrate. This further causes/encourages the growth of unwanted algae in the wider water volume. • The softscape and hardscape components may create pockets/portions of the water volume which are shielded from any circulation in the water volume. These pockets/portions of the water volume therefore stay largely static compared to the wider water volume. Waste from the fish may accordingly build up in these pockets/portions of the water volume. This results in poorer filtration of the pond/aquarium and therefore requires the need for regular tank maintenance/cleaning. • Replacing the nutrient rich base layer requires completely emptying the aquariums and/or ponds of softscape and/or hardscape and the gravel layer. This is laborious and time consuming. • Having a sufficient number of softscape/hardscape components for the amount of beneficial bacteria appropriate for the number of fish obscures the fish and further reduces the available volume of water for the fish to swim in. • Common hardscape components such as wood release tannins into the wider water volume, causing unwanted discoloration of the water.
