Balloon Ram
Balloon Rams are unique and can spark debate for aquarium lovers. Their balloon-like look comes from selective breeding. They’ve been bred to have more obvious features. Some appreciate the balloon ram’s unusual appearance. But, there are those who worry about the methods used to get this look.
Unique Appearance

Ethical Concerns

Tank Dimensions
The shape and size of a 20-gallon tank are very important for angelfish. If it’s a tall tank, that’s good news. Taller tanks give them room to stretch their fins. But if it’s wide and not tall, it might not be the best fit for them.
Size at Maturity
Knowing how big angelfish can get is key for their care. Remember, they can grow up to 12 inches. This may be more space than a 20-gallon tank can give. Keep a close eye on their size. If they start to outgrow their home, you might need a bigger tank.
