Origin And Distribution

Originally, the fish is from regions in Central and North America such as Mexico, Guatemala, Honduras, Nicaragua, and Northern Belize. Non-native populations of these species can be found in different parts of the USA like California, Florida, and Colorado. 

Others inhabit Nevada, Texas, Montana, Louisiana, and Hawaii. Nevertheless, this fish is not labeled as an endangered species despite its wide distribution.


The fish gets its name from the round markings near the tail. This fish has three black dots, one large dot, and two small dots that appear like ears, which very much resemble the famed Disney character called Mickey Mouse.

When it comes to color, this fish is available in gold, red, pale yellow, orange, and in some instances blue. The fins of this fish can have a pale yellow, red, or black-tinged color. Like other platies, this fish has a short, stout, and sleek profile.

They are also identified by their triangle-shaped heads and fan-shaped tails. Typically, female Mickey Mouse platies measure about 6 cm long and are relatively larger than their male counterparts, which measure about 4 cm long. 

Gender Differences

Although males and females appear similar at first glance, they have their differences. Generally, the fish is sexually dimorphic, meaning that both genders have different appearances.

As aforementioned, the males are smaller compared to their female counterparts. It is easy to identify the male fish because it features a more modified cloacal fin beneath the belly. 

This fin is known as gonopodium and is useful for mating for depositing sperm into the female platy. The tail fin is also more pointed in male platys than in female platys.

The females, on the other hand, have a fan-shaped cloacal fan. Mature female platies also have a rounder belly for carrying unborn fry. However, females don’t feature a vibrant color like males. 

Typical Behavior

The Mickey Mouse platy is a sociable and peaceful fish that rarely gets aggressive. They are also quite playful and get along with others when placed in a community tank. They love to swim in the mid-area of the tank. 

Mickey Mouse Platy Care

When it comes to caring for this fish, there is not a lot that is needed. This freshwater fish is quite easy to care for, making it an ideal choice for beginner aquarium owners. 

They are quite hardy and highly adaptable and do well in alkaline water conditions with a pH of between 7.0-8.2. If your tap water is soft, you may need to add more minerals to make it hard. This fish needs to be kept in water temperatures ranging from 64-77°F. 

Plus, you don’t need a large tank to keep them. Because of their small, the fish can flourish in a small tank with a small to a medium-sized substrate.

To ensure consistency in the water condition, it helps to check the water regularly. You can use a test kit for this.

The Ideal Tank Requirements

This fish can thrive well when kept in a 10-gallon thanks to their small size. Nonetheless, you may want to get a larger tank to provide more swimming areas for these active fish species. 

It is recommendable to place them in a group of between 5 and 8. Ensure that the females are more than the males.

Generally, the tank should be thickly planted with live aquarium plants to provide shelter and allow exploration. Plants also produce oxygen and consume CO2 and harmful nitrates.

Besides plants, you should layer the tank with a dark-colored substrate. This is a good choice since it closely mimics the riverbed sludge in their natural habitat. 

The substrate can include things like flat rocks, pieces of driftwood, twisted roots, and glass pebbles. However, the fish is not fussy about the material used in the layer since they are middle-dwellers.

Lights can also be an excellent addition to your aquarium. Not only will lighting the tank help with the process of photosynthesis for the plants, but it will also help your fish maintain a day and night cycle.

When decorating the tank, ensure that you leave plenty of space, especially in the middle of the tank. Otherwise, overcrowding will only make it difficult for this active, freshwater fish to play and explore. 

Don’t forget to include a sturdy lid cover on your tank. Like other platies, the Mickey Mouse can jump powerfully out of the tank if not well covered.

Diet And Feeding

The fish needs a well-balanced diet to grow and give birth to healthy babies.

In its natural habitat, the fish is omnivorous, meaning that it can consume most foods. While in the wild, it gladly consumes insects, fry, larvae, and algae. 

This platy species is not a picky eater and can eat flake, frozen, freeze-dried, or live food like bloodworms, brine shrimp, and insects. You should also include plenty of vegetables like zucchini, spinach, lettuce, or even cooked peas. 

A well-balanced diet will ensure that it gets the necessary vitamins and nutrients for healthy growth. Adults should typically be fed one meal while young ones can be fed two to three times a day.

Something else to note is that these fish species are more avid eaters than some of their tank mates. For this reason, it is highly advisable to place the meal in different places in the tank to ensure that they all get something to eat. 

The Best Tank Mates For Mickey Mouse Platy

Since the fish is a peaceful fish, it should be kept in a community tank with other peaceful fish. They especially do well when placed together with other fish species from the Xiphophorus family.

Some of the best tank mates for this fish species include:

1. Guppies

Live plants are an excellent addition to an aquarium hosting Guppies. Inside the tank, ensure that you feed them with a pelleted diet once or twice daily and frozen diets and veggies once or twice weekly.

They particularly like commercial foods such as quality flakes to remain healthy. The trick is to feed them a variety of foods to prevent them from getting bored with the same food.

As aforementioned, Guppies are livebearers and they can have more than 50 fries at any given time. To keep their population in control, it is highly advisable to keep the females and males in separate tanks or use tank dividers.

This may also be useful if you want to save the fry from being eaten by their parents. Also, always opt for smaller tankmates if you want the fry to survive.

Like the platy, the Swordtail is a freshwater fish that hails from Central and North America. It is closely related to the platy and the guppy fish species.

They are peaceful, friendly, and easy to care for. Although they are not shoaling, they make great companions for other peaceful fish species.

Swordtail fish loves to stay in groups of about 5 to 6 and requires a tank that measures 20 gallons. While you need to ensure that the aquarium features heavy vegetation, you won’t need to be picky about their substrate material since they are upper feeders. 

Naturally, they are found in freshwater sources like rivers, streams, and creeks. When kept in an aquarium, they flourish in water with moderate alkalinity of about 7.2 pH. The water temperature should range between 72- and 79 degrees F. 

The swordtail fish is omnivorous, with plant particles and insects making a large part of their diet in the wild. They will do well with a varied diet of protein-rich meals like meat and live foods and quality flake food.

What’s more, nutritious treats like brine shrimp, frozen and freeze-dried commercial foods, and algae wafers should also be included in their diet. Two to three meals a day will suffice, with the juveniles requiring more protein to grow.

Native to South America, it has a peaceful and non-aggressive nature and gets along well with other peaceful fish like the platy. It can, however, get under a great amount of stress when placed in a tank with aggressive fish.

Cory loves to school in a group of about 5 or more. They are very colorful and love to do a water dance, which is truly fascinating to watch. 

A Cory is a bottom dweller and loves to spend time scavenging for food. For this reason, it is recommendable to keep them in a tank with plenty of live aquarium plants and rocks to hide and explore. 

If you decide to choose this fish as a tankmate for your Platy, ensure that the tank has quality water conditions. Otherwise, they can get stressed and quickly catch a disease when exposed to a tank packed with harmful compounds like nitrates. 

When it comes to their diet, the Cory Catfish eats worms, larvae, plankton, and insects in the wild. In an aquarium, they enjoy shrimp pellets, fish flakes, algae rounds, worms, and tropical granules. 

Bloodworms and Daphnia are also good choices to treat this fish. Being omnivorous, you should feed them a varied diet to keep the healthy.

5. Neon Tetras

Min Tank Size: 10 gallons

Temperament: Peaceful 

Diet: Omnivorous

Care Level: Intermediate

Neon Tetras are easy to identify by their striking transparent bodies that come in beautiful colors like metallic red, green, and blue. Measuring about 1.5 inches on average, these fish are small and rarely grow large. 

Although small, they can be a bit feisty and should not be placed with Mickey Mouse Platy fries as they are likely to eat them. Nonetheless, they are peaceful and passive, and should be added to a tank with non-aggressive fish species.

Also, since they are a schooling species, you need to ensure that you house them in a group of 6 or more in a community aquarium. Being in the company of their own species makes them feel safe and secure. 

Because of this, these middle-dwellers are best kept in a large, freshwater tank. They thrive well in a fully-mature tank that measures at least 10 gallons.

How To Breed The Mickey Mouse Platy

This fish is a livebearing fish that can breed between 40 and 60 fries. Unlike some fish species which lay eggs, it can give birth to live you, also known as fry. 

This fish becomes sexually mature at 4 months. Hence, you may need to separate them as soon as possible if you don’t want to end up with a populous tank.

Since it is an ovoviviparous livebearer, the eggs develop and hatch in the female fish before birth. During mating, the females store the sperm packets, allowing them to reproduce for several months in a row without the need for mating. 

If you have both a male and a female Platy in your tank, then there is a high likelihood that the female is pregnant or will be very soon. You will know that the female is pregnant if they have a rounder and have what appears to be dots or fry moving.

Once fertilization takes place, they will give birth after 30 days. Nevertheless, the gestation period can be shorter if the water temperature is warmer. 

Unfortunately, the parents are likely to predate the juveniles once they are born, making it necessary to come up with strategies to safeguard them. One way to do this is to offer plenty of hiding spots for the fry to seek shelter.

Similarly, you may want to transfer the mother to a densely planted nursery tank where she will give birth. As she gives birth, the young ones will hide in the plants and you can eventually remove the mother. 

The other way is to use a breeding trap that will confine the mother and allow the fry to fall through the slits. However, this can be uncomfortable and distressing for the mother.

After several months, the juveniles will gain color. At this point, you can continue to raise them or sell them to friends or a local fish store.
