Angelfish are easy to care for and can live up to 10 years in captivity if they are provided with proper aquarium conditions. Because of their shape, this species prefers tall aquariums with a capacity of at least 20 gallons. However, if you want to keep several in a beautiful setup, I would highly recommend an aquarium that is 55 gallons or larger. Another advantage of purchasing a larger tank for your angelfish is that the increased space will offer a better feeling of security, and breeding parents will not be as quick to eat their eggs or hatched young.
When selecting a tank, make sure it's at least 20 gallons in capacity
Many angelfish pairs will need nothing special done to their aquarium, but others will not spawn unless careful thought is given to the aquarium set-up. With bare bottom aquariums it sometimes helps to paint the outside bottom of the tank a "matte" dark color. This cuts down on reflection and usually makes an angelfish pair feel more at ease. You may have to do this to a couple of the sides also. With some pairs, you may have to try covering the whole aquarium, try a bigger aquarium, or maybe turning off a light will work. Some angelfish pairs may require a dither fish to distract them or make them bolder. The key is experimentation.
How to set up an angelfish aquarium??
Angelfish Tank Set-Up: When setting up an aquarium to house your angelfish pair, remember that this is one fish where a tall aquarium must be considered for reasons other than aesthetics. It is not uncommon for properly cared for veil angelfish to reach 12 inches or more from the top of the dorsal to the tip of the anal fin. If a breeding angelfish pair is cramped, they may not feel secure. So, make sure you give them plenty of room. We recommend a 20-gallon "high" as the smallest aquarium to house a pair. Angelfish need to feel secure in order to do well and to breed freely. Their natural environment is one of slow moving water that has many hiding places such as roots and tall plants. Although, gravel is not recommended in the breeding set-up, potted plants and/or cured driftwood is fine. If the angelfish spawn on the plants or driftwood, remove these items until they spawn on the desired medium - spawning slate or MAG slate. After the angelfish pair has had a spawn or two on a spawning slate, they will usually continue to use the slate, even after you put the plants back in.
