The male angelfish, for example, have smaller and more pronounced genital papillae than in females.

But these may not be visible, except during mating periods. The males of the species can also show more aggressiveness or territorial behavior.

The angelfish usually has a life expectancy of between 5 and 8 years, depending on their quality of life and health.

However, a relevant fact regarding their life expectancy is that they are cold-blooded fish.

So they can live more or fewer years depending on the temperature of the water in which they live.

If the temperature is high, its metabolism will be high, if the temperature is low, it metabolism will below. But it will also have a less receptive immune system.

Care of the angelfish

It is important that the person who has an angelfish knows the needs of it. And more when the caregiver wants to add it to another aquarium, it is very common to die within a few weeks if you do not have the justify conditions.

Aquarium for angelfish

The aquarium for the angelfish must have a great height since the angelfish is taller than long. Otherwise, it could not move comfortably because his fins would protrude from the water or touch the bottom of the aquarium.

To house a single angelfish the aquarium must be at least 110 liters. For two specimens, the aquarium must have a minimum of 150 to 200 liters capacity.

And two males of this breed should never be placed together. People who have an angelfish are important to mature the aquarium for about a month if they want it to be in optimal conditions.

The maturation of the aquarium consists of developing bacteria that are beneficial in the water and eliminating those that are harmful.

So they can make a kit of beneficial bacteria to speed up the process and thus be able to introduce the first angelfish at 30 days.

If in 2 months there has been no problem, you can add another angelfish depending on the capacity of the aquarium.

Water quality

There are certain characteristics of water that must be taken care of. The parameters and conditions of the aquarium water is very important if the breeder wants the fish to be in the best conditions.

That is why the water temperature should be between 25 and 26 degrees Celsius. The pH must of the water should be between 6.5 and 7 and should be free of nitrogen compounds.

The temperature should never exceed 28 degrees or we would be shortening the life expectancy of the fish.

It is important that the breeder has available a thermometer and a water heater. It should also have a water filter with more capacity than the liters that the aquarium has, the most suitable is the waterfall type.

A filter that makes noise and generates movement in the water can stress the angelfish.

When the aquarium is cleaned, 20% of the water should be replaced every week, since it is a large fish and produces a lot of waste.
