Are Angelfish Hardy?

Angelfish are relatively hardy if you keep them under the right tank conditions. They can live up to 5 to 10 years when provided with basic amenities like good water and tank conditions. However, they can give an adverse reaction when the conditions are not favorable.

It is advisable to always put an even number of Angelfish in the tank. The odd one gets picked on and sometimes gets killed. They form cliques and move in pairs.

Growth: Angelfish are rapid growers. They can grow up to 6 to 10 inches in diameter within the range of 18 months. If the Angelfish are well fed, and under adequate water and tank conditions, they can increase more than you expect.

Tolerance: Angelfish are relatively hardy so they can, to a reasonable extent, tolerate harsh water and tank conditions. The only thing is that, when provided with their adequate needs and requirements (tank and water conditions), they tend to live longer.

Maintaining good condition will prevent them from stressing themselves to adapt to harsh conditions. But when provided with strict conditions, their lifespan reduces. They do not live as long as they can.

Compatibility with other fish: Angelfish will not do well with aggressive or territorial fish. They most likely don’t do well with other fish except if the fish are peaceful and submissive type.
