10 Gallon Tanks vs. 20 Gallon Tanks for Mickey Mouse Platies 

For a single pet, a 10-gallon Platy tank would do, but with a small group, you’d need extra space, so get a minimum of 20 gallons.

Setting Up the Tank

After choosing the appropriate tank size for your pet, you have to set up the interior to accommodate its needs. You can follow a basic livebearer tank guide, as most essential needs are the same, from aquascaping to aquarium tank tools. 

Aquascaping

Breeding Mickey Mouse Platies & Fry Survival Tips

In this guide, you’ll learn that livebearer fish breeding is different from the system of fish-scatterers because the reproductive cycle isn’t the same. With livebearers like Mickey Mouse Platies, your pets would birth their young alive without going through the egg stage. 

Setting up the Breeding Tank 

Get a separate Mickey Mouse platy breeding tank, install a mini breeding compartment in the main tank, or use a standalone mini tank. It’ll let you adjust the water conditions to appropriate breeding levels, preparing your chosen Mickey Mouse Platy adults for reproduction. 

Increase the water temperature to 75 – 80F, and ensure there’s at least 10 – 20 gallons of water. Add enough live plants to catch the fry after birth and protect them as they grow. 

Choosing the Breeding Adults 

Choose healthy adult Mickey Mouse Platies that are at least 9 to 12 weeks old for breeding. Remember that females are rounder and larger, while males are slender, smaller, and have a gonopodium (pointed anal fin). 

Pair one male Mickey Mouse Platy with two to three females to spread their aggression and reduce the stress on the females. For conditioning, ensure you feed your adult Mickey Mouse Platies more protein as the reproductive season approaches. 

Mating, Fertilization, Gestation, and Birth 

The male will pursue the females to mate and fertilize them. A single fertilization can lead to several birthing sessions, as your female Platies will drop 20-100 fry in batches. 

Upon fertilization, the female Mickey Mouse Platy would develop a boxy belly that darkens and becomes gravid. Within 30-45 days, they’ll deliver their fry. 

Fry Care 

Immediately after birth, remove the females from the breeding tank to protect the juvenile Platy fry because parents can eat their young. Since there’ll be no parent Platy to care for the new fry, it’ll be your responsibility to feed them. 

Feed them with finely crushed fry flakes and infusoria in their early days. As they develop larger mouths, you can add baby brine shrimp to their diets. 

During the fry stage, your baby Mickey Mouse Platy would be highly sensitive to poor conditions. So, ensure you make weekly water changes of about 25-35% to maintain pristine water conditions.

Common Problems: Shimmying, Stress & Fin Damage

Look out for common livebearer health issues that may plague your Mickey Mouse Platy fish when you slack in providing daily care. Most problems that can make a Mickey Mouse platy sick stem from poor water quality, improper breeding, poor diet, and genetic defects. 

Here are some common health problems and how you can manage them: 

Swim Bladder Disorder 

The most common symptom of poor Platy fish health is swimming struggles. They’ll sink rather than swim and sometimes float upside down in the tank. Swimming bladder disorder is a result of constipation from overfeeding. 

So, to treat your pets, start by fasting the fish and reducing their portions. 

Ich 

White spots on your fish’s body are a result of parasitic infections caused by poor water conditions. Immediately increase the temperature in the water to speed up the parasite’s life cycle and apply anti-ich medication on your pet’s body.

Columnaris 

Another common bacterial infection in Mickey Mouse Platies is cottonmouth, also called columnaris. Treat it by increasing the water temperature and ensuring your pet has access to anti-bacterial medication. 

Shimmying

Your Mickey Mouse Platy shimmying is the biggest sign of stress and poor water quality. Ensure the water conditions are correct and stable. Change the water and quarantine the affected fish for observation to ensure you provide appropriate treatment.
