Here is a youtube guide answering how big angelfish get.

How Can I Help My Angelfish Get Big?

1. Provide Them With a Proper Diet

Angelfish are entirely carnivorous and feed on invertebrates like worms, tiny shrimp, insect larvae, and even smaller fish.

Instead of feeding them prepared meals with fillers like potato and wheat starch, you can offer them high-protein prepared foods such as Fluval Bug Bites.

This will improve their growth rate and help them to reach their full potential size.

2. Maintain High Water Quality

Angelfish are ferocious meat-eaters, therefore their waste contains a significant amount of nitrogen.

This nitrogen becomes ammonia, nitrite, and eventually nitrate which is very dangerous to your fish.

Excess nitrate poisons fish, causing breathing difficulties, slowed development, brown gills, lethargy, and death.

To reduce nitrate levels, you should do frequent water changes and vacuum the gravel to remove uneaten food and fish waste.

Also, you can add live plants and specialty filtration media that cultivate anaerobic (oxygen-hating) denitrifying bacteria that help to break down these harmful toxins.

3. Add Suitable Tank Mates

Compatibility issues between angelfish and other fish are one of the most crucial factors to consider.

You should avoid fin nippers like Tiger Barbs and Giant Danios that are aggressive enough to damage the trailing fins of your majestic angelfish.

Instead, keep them with smaller but strong peaceful fish like Swordtails, Black Ruby Barbs, or Hatchetfish.

In addition, smaller community fish such as Guppies and Neon Tetras are excellent companions to Leopold’s Angelfish.
