Step 2: Equipment for aquarium decorations


For beginners, it is advised large aquariums where it is easier to control the parameters of the water necessary for the survival of the fish. In small aquariums, the environment is more unstable and the amount of fish you can have is much smaller.



Lighting for tropical aquariums can range from simple and small lamps to something more elaborate for planted aquariums. If you are not going to plant natural plants, opt for a more basic light bulb.



Filters are essential to clean the water and keep it oxygenated. Choose filters that perform a mechanical, chemical and biological filtration, the latter being the most important.



There are two types of the most commonly used heaters: those that are placed hanging at the back of the aquarium and those that are submersible. The temperature in tropical aquariums should be around 25ºC.



Sand with 3 to 5 mm is a good option for the substrate, allowing the biological filtration and fixing of artificial plants or other decorative elements. If using natural plants should opt for several layers of substrate: hummus, some gravel, and sand.



The plants placed in the aquariums can be true or plastic. For fish, both serve as hiding places. Aesthetically, true plants look better but require more care.



There are several options for decorating the aquarium: rocks, logs and other types of objects, such as the traditional sunken boat. The aquarium decorations should provide hiding places to make it more functional. Before introducing any object, you should only wash it with water.
