Setting up an Angelfish Aquarium
Angelfish grow to be pretty large fish, so it is vital to have a large enough tank to support them. Angelfish that live in undersized aquariums are often unhealthy, unhappy, and aggressive. I would suggest a tank of at least 20 gallons to support a few Angelfish. This is especially important if you plan to keep other tank mates. While they can be great community fish, Angelfish are still in the cichlid family and become territorial if space is limited. It is always better to have more space than not enough space!
Angelfish tend to be pretty hefty eaters, which means a lot of waste in your fish tank. Make sure you have a good filter that can handle these type of fish. While a good hang on back filter will work, I would highly recommend purchasing a canister filter. Canister filters can process a lot more water than HOB filters, and they tend to be a lot more effective for freshwater aquariums.
Substrate
When setting up your Angelfish aquarium, the first major decision you need to make is the type of substrate you are going to use. If you are new to fishkeeping, I would recommend going with a simple gravel substrate. Though gravel tends to trap a lot of waste, it is extremely easy to clean and doesn’t require a ton of upkeep. It is also fairly cheap to purchase
If you are more experienced with aquariums, adding sand as a substrate can be a beautiful addition. Angelfish are natively found in the Amazon Basin in South America, so naturally they are more familiar with a sandy bottom. Sand will give your tank a more realistic, natural look, but can be more difficult to clean.
