Do guppies need other guppies

While technically guppies aren’t schooling fish, they do tend to stick around in a group. To answer the question of whether you can keep guppies alone, I’d say no, guppy fish cannot live alone because they’re social fish that require company. Plus, having only a single fish in an aquarium is a pretty sad sight. (source)
What Do Guppies Need in Their Tank? Guppies grow to an average of 2 inches long, so the smallest tank size we recommend is a 5-gallon aquarium for a trio of guppies. But given how quickly they reproduce, a 10- or 20-gallon aquarium would be more appropriate in the long run. (source)
Generally, you should keep guppies in groups. And ideally, you should keep at least a trio of guppies in at least a 5-gallon fish tank. You can keep more than a trio of guppies but then you will also need to increase the tank size of your fish tank according to the number of fish you are going to keep in the tank.

But is it possible? You can keep only male guppies in a tank. However, when you keep only male guppies in a tank, you will see a lot of aggression and bullying among them. To spread out the aggression, it is recommended to keep at least 6 male guppies in a male-only guppy tank. May 14, 2021 (source)
Yes, you can have two male guppies together. Male guppies have no problem cohabiting. With that said, male guppies can sometimes exhibit aggression towards other males. For example, they may chase each other to assert dominance or fight over a female. (source)
Can guppy fish and betta fish live in the same aquarium? Yes! However, since betta fish is semi-aggressive, it is important to take a few precautions in order to protect the guppies. Oct 26, 2021 (source)

2 to 3 years Guppies live an average of 2 to 3 years. In the wild, guppies live an average of 2 years. However, in captivity guppies can live anywhere between 2-5 years. Although the average is typically 2-3 years in captivity, if properly cared for, guppies have been known to live up to 5 years. Feb 25, 2022 (source)
While it’s possible to keep guppies in an aquarium that does not contain live plants, they really love their live plants. They provide cover and also have many other great benefits on your tank. Live plants are known to clean your water by consuming nitrates, as well as balancing the water parameters. (source)
A 5-gallon aquarium is suitable for a group of 4 or 5 MALE guppies. Guppies are live-bearing fish, meaning the females give birth to live, free-swimming baby fish. (source)
Note: Keep in mind that Guppies should be kept in 3 or more since they live in shoals. If you are keeping them in a bowl then only keep one type of sex, otherwise they will start breeding and you will need more space. May 26, 2017 (source)
But, as a minimum, 3 is the magic number – 1 male and 2 females. Keeping 2 males and 1 female isn’t a good idea since males are extremely competitive when the mating phase begins. And, with guppies, the mating phase begins pretty much daily. Jan 20, 2022 (source)
Guppies should be kept in trios – 2 females to each male. Yeah, this is so important we’re sayin’ it twice. Not only does this better the chances of reproduction, but female guppies are also less likely to become territorial than males- so you’re more likely to keep a peaceful aquarium.

To dispel misinformation and myths once and for all, guppies cannot change sex and are not hermaphrodites. Females need males to fertilize their eggs and produce offspring, but they will also store the males’ sperm several months for when males are not available. Jan 20, 2022 (source)
One of the most common signs of aggression is when one guppy is constantly chasing another. This is because they’re trying to assert their dominance by scaring them and attacking them. While it occurs more in males, it doesn’t mean females won’t do it either (you’ll find out more about this later). (source)
