A protein skimmer is a device used to remove organic compounds such as food and waste particles from water. It depends on the specific conditions of the tank if you need one or not therefore making it optional.

Some benefits of Driftwood in a aquarium

Driftwood helps boost the immune systems of your fishes. When driftwood is submerged, natural tannins will slowly leach into the aquarium water. These tannins create a slightly acidic environment that helps to keep viruses and disease-causing bacteria at bay.

The filter in the fish tank keeps the tank clean. It'll keep out any harmful bacteria from growing in the tank. And it keeps the take to have clean water for the fish to breathe and stay healthy.

The heater is an essential item, needed for maintaining the proper temperature for the fish's health.

The nitrogen cycle is a chain of biological reactions that produces chemical results. Then nitrogen cycle begins with fish waste material, which produces ammonia. Ammonia is very toxic to fish and, in the small confines of an aquarium, could eventually kill them. But fortunately, ammonia is "food" for nitrifying bacteria, which are always present in water. The nitrifying bacteria "eat" the ammonia, producing nitrite. Other nitrifying bacteria "eat" the nitrite, producing nitrate. Since nitrate is relatively harmless to fish unless it accumulates in large quantities, the toxic effects of the ammonia and nitrite are canceled out by the biological food chain. You need to filter aquarium water and change a portion of the water regularly in order to keep the nitrate levels low. The nitrogen cycle is what keeps the chemical balance of water at life-sustainable levels for plants and fish. That's why you must test your aquarium's water often and make necessary adjustments by adding activated carbon, ammonia neutralizers or water softeners as your water test levels indicate.

The lid holds the light fixture, and provides an enclosed environment to the aquarium. It also helps slow the rate of evaporation of water. It is an essential piece of equipment.

Freshwater angelfish have tall vertical dorsal fins and long vertical anal fins. Their colors and patterns, while striking, are not as dramatic as those of the ocean angels. Both have long ventral fins that look like tendrils.

-Angelfish like to eat jellyfish and algae
-They are very intelligent and can recognize their owners (when kept as pets)

Driftwood and large rocks so the angelfish could hide and also lay their eggs.

# data[].attributes.body
They like large broad leaf plants and driftwood that is arranged vertically to simulate downed branches and trees and also like floating plants for shelter.

fine sand/mud will make the best substrate for them and a small amount of water flow so they don't scrape their fins since they like to go to the bottom for food.

# data[].attributes.body
Angelfish prefer slightly warmer water with a pH between 6.8 and 7.8 and a temperature between 78 and 84 degrees. They grow quite large so they require a freshwater tank will at least 20 gallons or larger. tall aquariums are also best.

# data[].attributes.body
They are omnivores and will thrive on mostly meat flavored flakes.

Angelfish are native to a large area of tropical South America, including much of the amazon River system. In their natural habitat, they are found almost exclusively in quiet, slow moving water. In the wild they prefer dimly lit areas, under overhanging vegetation or among trees that have fallen into the river.
