Guppy and molly temperament.
Knowing the temperament of fish before adding it to your aquarium is essential.
Being aware of guppy and molly temperaments will help you detect the issue in your fishes when they show strange behavior.
Guppies are peaceful fish species and love to live in a community tank.
Guppies are non-aggressive and will not create any issue with mollies.
However, some conditions can trigger aggressiveness in your guppies, like illness, stress, and an improper ratio of male and female guppies.
If you have more male guppies in your tank and few female guppies, it can be a reason for aggressiveness in the male guppy.
Male come will fight each other to mate with the female guppy.
Also, more male guppies and a few female guppies will make your female guppy come under stress because of the constant chasing of male guppies for reproduction.
Consider keeping the guppies in the ratio of 2:1.
Keep two female guppies for one male guppy.
You can also go for keeping three female guppies for one male guppy.
Molly fish are also a peaceful species and do great in a community tank.
Mollies will not be aggressive until you provide them with good living conditions and a big enough space to swim freely.
Mollies will show signs of aggression when you keep them in an overcrowded tank or with other aggressive tankmates.
Why molly will be aggressive, it will target guppies because of their smaller size and colorful fins.

How can we keep guppy and molly together?
Keeping guppies and mollies together is not a difficult task.
However, there are some precautions you have to take when adding mollies to your guppies aquarium:
- Keep your guppies and mollies in a large size tank.
- Create plenty of hiding places for mollies and guppies.
- Add lots of live aquatic plants to your guppy-molly tank.
- Monitor feedings carefully.
- Control population of guppies and mollies.
- Protect your guppy and molly fry
- Perform a regular water change
Large size tank
Mollies and guppies both require enough space to live comfortably.
Mollies are peaceful fish, but if we keep them in the overcrowded tank, they will show signs of aggression.
Mollies will chase and try to hurt guppies by nipping their fins in aggression.
So, for not letting this happen, keep your mollies and guppy in a large enough tank where they can live and swim freely.
Follow one inch one gallon rule, one inch of fish per one gallon of water.
Mollies can be 4 inches long, whereas guppies can be 2.4 inches long.
So, if you have 20 gallon tank, consider keeping three guppies and two mollies.
Someplace will be covered by plants, substrate, and other decors.

Guppies and mollies are both life bearers.
If you keep male and female guppies together in the same aquarium, they will breed out of control.
Guppies and molly can get pregnant every 30 days.
Because they both can get pregnant right after releasing fry and the gestation period of mollies and guppies is 30 days.
Pregnant female guppy can give birth to 5-120 fry at a time.
Pregnant female guppy can also give birth to 5-70 fry at a time.
Guppies and mollies can carry sperm with themselves and can be pregnant multiple times.
Mollies can use the sperm for three months to get pregnant multiple times.
Whereas guppies can use the sperm to get pregnant multiple times for a lifetime.
Adding only female molly and guppy to your aquarium also has possibilities of them getting pregnant because of previous encounters with male molly and guppy.
So, controlling the population becomes essential when keeping mollies and guppies as they can get your aquarium overcrowded.
Keeping only one gender for each molly and guppy also will not solve the problem of population control.
Guppies and mollies can reproduce with each other when they don’t find the opposite gender in their species.
If you cannot control the population of molly and guppy, you have to keep only male guppy and molly or only female guppy and molly.

Also, don’t keep the pregnant molly or guppy in a breeding box because it can cause stress to them, and they can abort the fry.
Separate the pregnant guppy and molly from their fry right after they give birth to them. They will eat their fry otherwise.
If you are moving your pregnant guppy and molly to a separate tank, make sure to adjust the water parameters as before for your pregnant fish.
Perform a regular water change
More breeding will result in more molly and guppies in your tank.
Usually, molly and guppy will eat the fry, but there will be some fry that will save themselves and grow.
So, more mollies and guppy will be there with time.
