Questions

What size tank does a Angelfish need?

At least 55 gallons. Adults grow to about 6 inches, so plan for the adult size, not the size at the store.

What temperature does a Angelfish like?

76 to 82 degrees Fahrenheit, with a pH of about 6 to 7.5. A steady temperature matters more than hitting one exact number.

How many Angelfish should I keep together?

One is fine. If you keep more, keep one male, since males fight each other.

What do Angelfish eat?

Flakes, small pellets, frozen foods. Feed twice a day: a small pinch they finish in about 2 minutes, a little more for bigger fish.
