What Are The Different Freshwater Angelfish?
You’ve probably heard of freshwater Angelfish. These guys are super cool and come in many different types, each with unique looks and personalities. Here are a few of the most well-known ones:
1. Altum Angelfish
These guys are the biggest in the group and are usually caught in the wild. They’re also called Orinoco angelfish or blue Angelfish. They need more TLC than the others since they come from the original habitat.
- Mature Size: 7-10 inches
- Color: Silver, gold, and black
- Characteristics: Largest Angelfish
2. Albino Angelfish
These fish are unique since they have no pigment and pink eyes. But if you catch them in the right light, you can see some pale gold stripes along the sides, which is pretty cool. They’re a natural genetic aberration, which is wild.
- Mature Size: 6 inches long
- Color: Pink/white
- Characteristics: No pigment and pink/red eyes
3. Black Lace Angelfish
It’s another type that’s interesting. Black Lace Angelfish came from a careful selection of silver and zebra angelfish with extra dark genes. They’re not very active swimmers and can get scared quickly, so keep them somewhere quiet.
- Mature size: up to 10 inches
- Color: predominantly black-colored body
- Characteristics: not an active swimmer
4. Gold Angelfish
Gold Angelfish, on the other hand, is pretty flashy. They feature a split pattern of silver and gold and have long, trailing fins that you need to watch out for. They take a while to develop their rich golden hue, but they’re worth the wait.
- Mature Size: 6 inches long
- Color: Golden
- Characteristics: Stripeless
5. Koi Angelfish
Koi Angelfish are pretty cute. They have a red patch beneath their eyes when they’re young, which fades as they grow up. Some have patches of black, but they lack stripes. And get this; their orange tone gets darker when they’re stressed!
- Mature Size: 6 inches long, 8 inches deep
- Color: White, yellow/orange, black
- Characteristics: Tricolor with unique markings
6. Leopard Angelfish
Leopard Angelfish trace their roots to common Angelfish. They have spots on their sides instead of stripes, and you need to keep the lighting as close to natural as possible to maintain those spots’ clarity.
- Mature Size: 6 inches long
- Color: Black and golden yellow

- Color: Silver
- Characteristics: Adults are generally hardy, while juveniles can be pretty fragile.
9. Veil Angelfish
Veil Angelfish are the most popular, with over-the-top fins in every color and pattern. They’re pretty slow swimmers and are more prone to fin and tail rot. And those flowing fins are stiff for nippy tank mates to resist.
- Mature Size: 6 inches long
- Color: Variable
- Characteristics: Long, flowing fins
10. Zebra Angelfish
The Zebra Angelfish has four to six stripes across the body, including the one through the eye. They’re smaller than the others but are faster and more active swimmers. And some develop red eyes when they’re fully mature!

Each type of Angelfish has its unique look and personality, so you can pick the one that speaks to you the most.

Do Angelfish Grow To The Size Of Their Tank?
