Can male guppies live together

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. Keeping a male-only guppy tank is totally possible. May 14, 2021 (source)

Remove Constant Aggressors. If there’s a guppy in your tank that constantly acts aggressive, then you should remove them from the tank and place them in another tank. If you can’t do this, then you should consider giving them back to the pet shop or finding another home for them. (source)
The great thing about mixing different species of guppies is that they all thrive in the same water conditions. They also recognize each other as belonging to the same species, despite their differences in appearance. Just remember that guppies will mate with each other monthly. 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)
Now you know that you can keep male and female guppies together in a tank. And for the best success and happiness, adding lots of hiding places, keeping more females than males, and keeping the tank conditions perfect are key. (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)
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)
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.

Anyway, to cut a long story short, yes, male guppies fight, and yes, if their fins are repeatedly damaged then problems like finrot can occur. They may calm down once a pecking order is established, but don’t bank on it. (source)
Male guppies are always smaller than female ones. This means that you can accommodate 10 of them in a 10-gallon tank without an issue. But, a female guppy is 2 inches in size. If you plan to keep only females, you will need to limit their number to 5 per 10 gallons of water. Oct 17, 2020 (source)
Technically, you can keep 2 guppies in a 3-gallon tank. This tank size will however be too small because guppies are active fish. Furthermore, it will be hard for you to keep the water perimeters stable in such a small tank. (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)
Male and female wild guppies generally live for around two years, the same as captive guppies. Jul 24, 2021 (source)
So to conclude this article: yes, guppies and betta fish can live in the same aquarium. You will have a bit more work feeding your betta separately and you will also need to purchase live plants, but it is doable. Oct 26, 2021 (source)
