Adult Size & Lifespan

The average lifespan of an angel fish is 10 to 12 years, but it all depends on the individual. Some can live up 18 or even 20! Fully grown adult angelfish reach a body length three inches long with males being slightly larger than females in comparison to their structure-based differences
Females have smaller more rounded bodies when compared against male counterparts who tend towards having thicker holiest near fins (though this isn’t always noticeable).

Appearance & Behavior


Angelfish are one of the most beautiful and unique aquarium fish with long, spectacular fins. They also have an arrowhead shaped body that makes them stand out from other similar-looking breeds . Like all Angelfinned species , these peaceful creatures can be sudden or even aggressive at times but for the most part they stay calm in your home aquarium.
Fins make up more than half their total length so it’s important to keep yours clean! These magnificent flyers will show off beautifully if you give them ample room; just remember not too much algae growth because this impacts oxygen levels within liquid environments which could leadto complications such as difficulty breathing.

Colors, Patterns, Fins, and Sex Differences

Angelfish come in a variety of colors, with the most common being silver.

However there is also gold and black angelfish that have been seen on occasion, they can be identified by their lack or presence stripes across its body as well-defined markings become less noticeable over time until adulthood when only four vertical lines remain – three along each side (dorsal) near where you would find your spine if looking at it headon while undergraduates usually don’t lose all traces until afterwords because these fish grow very fast!


There’s a lot going on with an angelfish, so it’s important to know the signs of mood and stress.

When they’re stressed or sleeping their colors will appear duller than usual- but this isn’t always true!

Healthy well nourished fish live in vibrant hues while males have bolder coloration during breeding season because he wants females attention from across his territory ̶ though both can change at any moment depending how happy you make them feel

Typical Behavior


Angelfish are active, showy fish that swim in the mid-levels of an aquarium. They weave between plants with enough room to claim their own territory and can be found mostly diurnal (more active during daytime than at night). When housingangelfishes together because there’s not enough space for each individual fish or you want them close by so they don’t feel lonely; it is important Alto keep some distance between individuals if possible-this will help prevent fighting among group members!

The angelfish is a social species, but it prefers to keep its distance from other similar-looking individuals. This means that these fish are less likely than others in your tankb range of schooling behavior and aggression levels when competing for food or territory – although they still Vigorously defend themselves if necessary!

Angelfish Care & Tank Requirements

Angelfish are a perfect fish for those looking to have an easy going, hardy pet. The only requirements needed in order care of them are tropical freshwater with slow moving current and food that replicates their natural habitat- an omnivorous diet will do just fine!

Habitat and Tank Requirements


The angelfish is a schooling fish that can be found in warmer waters of the Amazon Basin.

They require soft, acidic water with plenty of plants and sunlight for their natural habitat to flourish, provide this type environment by using sand or mud as your substrate along with some rocks on top-the more room there are between these surfaces so they have space do explore below themselves (which interests them greatly), the happier they will become!

Provide your freshwater angelfish with as many hiding places and caves in the tank to make them feel at home. Provide native plants that are common along Amazon rivers, such as Amazon Sword or Anacharis (a type of aquatic moss). Avoid using floating vegetation because it will block out light needed by this fish species when they need access during nighttime hours; plus over crowding isn’t good either!

Tank Conditions

The ideal tank conditions for angelfish are:

Water type: Slightly acidic, slow-flowing freshwater
Tank size: Minimum 20 gallons, plus 10 gallons for every extra fish
Water temperature: 75–82°F
Substrate: Soft sand or mud
Tank setup: Plants, caves, strong lighting
Acidity: 6.8–7.0 pH
Water hardness: 4–12 dGH
Filter: Yes, to provide a slow current and keep the tank clean
Pump: Not necessary
Bubbler: No, the filter can provide sufficient aeration without the use of a bubbler
Lighting: The plants in your aquarium will be healthier if you provide them with standard lighting to mimic what they would experience naturally outdoors. This includes fluorescent lights, incandescent bulbs or even sunlight!
Water heater: Yes, to maintain a tropical water temperature

To prevent your angelfish from becoming stressed or ill, give it consistent water parameters in the tank.


freshwater diseases affect angelfish in captivity, including:
Finrot is a common illness that causes red scaling on the fish’s body. This can be prevented with proper water quality and diet choices for your pet angelface! If you notice any signs of this condition taking hold or have been catching an unhealthy looking fellow member then don’t hesitate to contact us so we’ll get it checked out right away.



Ich, or white spot disease can be caused by stress which usually results from poor tank conditions. The protozoan parasite Ichthyophthirius multifiliis causes ich spots on the fish’s body and also leads to lethargy and lack of appetite among other symptoms in addition itchy skin rashes at times as well! To treat this just add one teaspoon salt per gallon into your existing water while increasing its temperature by two degrees (which will speed up longevity).


Dropsy is an illness that can affect your freshwater fish. It occurs when the immune system becomes compromised, which allows bacteria to take over and causes symptoms such as bloating of organs or tissues, protruding eyes (usually), rapid breathing due in part by swelling around gills – this leads them not be able move around well enough while they’re infected because their body has no space left for air bubbles underneath all those extra layers causing shortness breaths since there isn’t much difference between inhaling/exhaling anymore.
You’ll want treat dropsies with antibacterial medications prescribed by vet care professionals along side adding ⅛ teaspoon Epsom salt per five gallons water changed weekly.

Fin Rot

Fin rot is a disease that causes shredded, milky fins and difficulty swimming. It can be caused by fluctuating water parameters or bacteria such as Columnare and Aeromonas species in the genus Flavobacterium.

The only treatment for this infection would involve cleaning your tank with 20–50% changes at least twice per month to remove any suspect organisms before they spread further into other areas of an aquarium, otherwise you will need antibiotics from your veterinarian if there are widespread infections present on their surface layers near fleshy tissue (healing takes place over time).

Tank Mates

The angelfish is a social, curious fish that thrives in an environment with other similar species. But when it comes to housing them? Be careful! This territorial and aggressive creature can get out of control if you don’t keep its needs fulfilled – like enough space for swimming around or hiding spots (they love branches).

Great tank mates for angelfish are:

  • Other angelfish. Angelfish can be housed in groups of up to six, as long as the tank is big enough to help them avoid conflict.
  • Other compatible cichlids, such as discus and dwarf cichlids
  • Dwarf gouramis
  • Mollies
  • Plecos
  • Pictus catfish

The angel fish is a peace-loving creature that should not be housed with other tanks or wild caught seafood because it can harassment the crabs, shrimp and other invertebrates.

Diet and Feeding

Angelfish are known to eat a diet of small live prey, including insects and other crustaceans in the wild. Replicate this menu by providing your angel with high-protein shrimp or worms that they can chow down on! In addition offer them blanched spinach every day – just make sure you give it only when there’s no more food left over from their previous feedings so as not strain too much upon yourself.
If possible also add some aquatic plants for added beauty throughout these important areas within both outdoor tanks where patio predators thrive without any natural.


The easiest freshwater fish to breed are angelfishes. They reach sexual maturity between six months and one year of age, so you can expect them to start breeding in your tank around this time too! To create a nursery for these beautiful creatures follow these simple steps:
Fill up an aquarium with room-temperature water as per recommendation on the label – don’t use cold or hot fluids because that could kill babyAngelfishies plants; 2 ) Add some floating plant leaves (they should form roots before planting); 3a+b retriever any unattached babies from their parents’ beds if possible

To help your school of angelfish pair up, create a separate 20-gallon breeding tank for each male and female. Make sure the water is slow flowing with temperatures at 82°F–and provide them some anacharis or PVC pipes as spawning surfaces! If you want even more success then feed these guys high protein diets four times per day made from tubifex worms or bloodworms mixed in blenderized fish meal (blend until it’s powder).

Move the pair to a breeding tank and watch their behavior. When the female lingers next to an areas where eggs will be laid, she is getting ready for her monthly harvest!
The male can fertilize externally so there’s no need in dipping him constantly – he does all of this work while looking after his pregnant wife anyway!. He might even provide some protection around these fry by chasing away any potential predators or competitors that come into range (like other fish). Watch closely though; if something seems too risky then remove them immediately as once they start feeling threatened towards each other.
