While your siblings can teach you a lot of things and generally always have your back, they can also drive you crazy, “borrow” your clothes, and rat you out to your parents every now and then.

No matter how much they bother you, your siblings are integral parts of your life. well, at least for some zodiac signs. Some horoscope signs need siblings in their lives. They need that support almost as much as they need someone to tell them to get their sh*t together.

Then there are the zodiac signs that could do without siblings. Maybe they’re already only children, or they find support in friends, but a few zodiac signs could take ‘em or leave ‘em.

I can’t speak for all Aquarians, but having a sister is one of the most important things to me. Not only is she incredibly kind, caring, and supportive (gotta love Pisces), but she’s also not afraid to practically shake me by the shoulders and tell me to get my head out of my butt.

Honestly, I’m not sure I would be even a quarter of the person I am today if it weren’t for my sister. And while we still argue over small, dumb stuff – which never really lasts more than a few hours – we still have each other’s backs.

If you feel the same way about your own siblings, then you understand when I say that I need my sister. Maybe it’s my Aquarius nature, but I think of my sister as my best friend.

You don’t have to be super close to your siblings for them to matter to you, but even when you don’t get along, they can bring a lot of benefits to your life. Plus, according to science, having siblings can be good for your health.

Siblings can help you be more selfless and empathetic to others, as well as positively impact your mental health. In times when you’ve felt lonely, unlovable, or self-conscious, having a sibling to remind you that you’re actually amazing – even if you know they’re right, and even if you’re not close in age – can help boost your mental health and how you see yourself.

Plus, having a sibling is like having a constant support system, no matter how far away you are from each other, because you know that they’ll always have your back. So, you could say that siblings are pretty essential, especially for these zodiac signs.

According to astrology, here are the zodiac signs who need siblings in their lives, based upon their horoscope personality traits.

1. TAURUS (April 20 - May 20)

Taurus needs siblings because it’s in his nature to protect. He’s the sibling who will fight your bullies for you, be your biggest fan, and teach you everything you need to know as you grow up.

You can almost guarantee that, while he still might annoy the heck out of you, you can look back fondly on having him as a sibling. Without you, he couldn’t be the caring person he is today.

Taurus needs someone he can protect and support – and there’s no one better for him to do that for than his siblings. It doesn’t matter if he’s younger or older than you, if he’s your best friend or you always fight – what it comes down to is the fact that you’re family, which means that he will always be there to stand up for you and show you the ropes.

2. GEMINI (May 21 - June 20)

Gemini can sometimes be a frazzled mess, but having his siblings around calm him and makes him feel like he can do anything. Without his siblings, Gemini would have no one to push him in the right directions, make good choices, or teach him how to be the amazing friend everyone knows him as.

Gemini needs siblings in his life because he needs someone to look up to. Gemini can sometimes get caught up in his thoughts, and he can be restless and impatient, but having siblings to look up to (even younger siblings) makes him feel like he has role models to inspire him and teach him what important in life. In short, siblings make Gemini a better person.

3. CANCER (June 21 - July 22)

Cancer may go through a lot of relationships in life, but one relationship that will never fade will be the relationship he has with his family. He knows that siblings can be crazy annoying, but he’s also a big believer in the phrase “blood is thicker than water.” That means, even though your family can get on your nerves, you always stick with them.

Cancer needs siblings in his life because he needs someone to take care of. He likes being the sibling you can call in the middle of the night to help you out of a jam or during the day, just to have lunch together. It may sound cheesy, but he likes being the sibling that would do anything for his family.

4. SCORPIO (October 23 - November 21)

Scorpio is definitely one of those siblings you always find yourself fighting with, but you can’t deny that he’s always got your back, too. Siblings are important to Scorpio because, even though you are stuck with each other, he knows that you’ll never judge him. He might have a hard time opening up to others, but he knows that he can always come to you to chat, vent, or just hang out.

Scorpio also needs someone to stand up for. He can be very protective of his relationships, and the relationships he has with his siblings are no different. He loves deeply, and when he really cares about you, he tends to being very protective. You can count on him to stand up for you (even if you’re not around) because you matter to him.

Pisces is the sibling that leans on his siblings for constant support and love. When Pisces makes connections with people, he makes them for life. So, even if you are family, there’s a good chance Pisces sees you as a best friend, too.

What make siblings so important to Pisces (and why he needs them in his life) is that they are people who can relate to and understand him without judgment, which is all he really wants in life.

Pisces is one of those zodiac signs that needs siblings, but his siblings need him, too. There's a mutual sense of support and respect between Pisces and his siblings; a relationship that will last for a very long time. No matter how far the distance between him and his siblings, there will always be a strong connection.
