Aquarium Setup Angel - Blue Neon
Aquarium Filtration
Use an efficient external canister filter or suitable internal filter that provides reliable biological filtration and moderate water movement. Regular partial water changes help maintain clean, stable conditions.
Aquarium Plants
Live plants such as Amazon Swords, Vallisneria and Java fern provide shelter and create a natural South American environment. Maintain open swimming areas between planted sections.

Fine sand or smooth, rounded gravel provides a suitable foundation for planted aquariums and complements the fish's natural appearance.
Aquarium Decorations
Arrange driftwood, smooth stones and tall plants to create vertical structure and sheltered areas. Provide generous open swimming space and sufficient aquarium height for the angelfish's flowing fins.
