What is a Mickey fish?

A Mickey fish, also known as a Mickey Mouse platyfish or a Mickey Mouse fish, is a freshwater aquarium fish that gets its name from its unique Mickey Mouse-shaped tail fin. Mickey fish belong to the platyfish family (Xiphophorus) and originate from Central America. They are small, peaceful fish that make excellent additions to community tanks. Here are some key facts about Mickey fish:

Origins and Taxonomy

Mickey fish are a strain of platyfish that were first bred in Asia by hybridizing variatus platies and swordtails. They were given the name “Mickey Mouse” fish due to their caudal fin shape. The scientific name for Mickey fish is Xiphophorus maculatus. They belong to the family Poeciliidae.

Natural Habitat

In the wild, platyfish like Mickey fish are native to freshwater streams, canals, and coastal rivers in Central America and Mexico. They prefer slow-moving, heavily vegetated waters. Mickey fish inhabit shallow waters that are murky and warm, with a temperature range of 70°F to 80°F.

Species Information

There are several different varieties of Mickey Mouse platies available today. Here are some of the most popular types:

  • Red Mickey: Bright red colors on the tail and fins
  • Blue Mickey: Deep blue hues on the tail
  • Tuxedo Mickey: Back and tail are black, while the belly is white
  • Sunset Mickey: Oranges and yellows on the caudal fin
  • Green Mickey: Dark green tail and accents

Appearance and Size

Mickey Mouse fish have oval-shaped, flat bodies that are wider in the middle. Their distinctively-shaped caudal fin resembles the face of Mickey Mouse, complete with round “ears.” Mickey fish grow up to 2 inches long on average. Males tend to be slightly smaller than females in size.

Colors and Markings

Mickey fish can be found in a wide range of bright colors and patterns. Here are some of the most common color variations:

  • Orange Mickey fish with black spots
  • Red Mickey fish with black trim on fins
  • Yellow Mickey fish with black tails
  • Calico Mickey fish with splotchy orange, black, and white
  • Mickey fish with red tails and blue bodies

Mickey Mouse platies typically have darker colors on the back and lighter shades on the belly. The unique tail is often yellow, orange, or red in hue.

Distinguishing Features

The main distinguishing feature of Mickey Mouse fish is obviously the tail shape. However, Mickey fish also have these defining characteristics:

  • Large dorsal fin
  • Pointed anal fin
  • Small mouth
  • Prominent eyes
  • Concave forehead

Temperament and Behavior

Mickey Mouse fish have peaceful, social personalities. Here are some key facts about their temperament:

  • Get along well with other peaceful community fish
  • Do best in groups of 3 or more
  • Relatively active swimmers that utilize all areas of tank
  • Males may chase each other occasionally
  • Generally not aggressive or territorial

Tank Conditions

Mickey Mouse fish thrive in stable, comfortable water conditions. Ideal tank parameters include:

  • Temperature between 70°F to 82°F
  • pH between 7.0 to 8.0
  • Hardness between 10 to 20 dGH
  • Low to moderate lighting
  • Planted tanks with plenty of hiding spots

Mickey fish are adaptable to a wide range of water parameters as long as extremes are avoided. Perform regular partial water changes to keep nitrates below 20 ppm.

Compatibility with Other Fish

Mickey Mouse platies are very peaceful and get along well with many small community fish. Good tank mates include:

  • Other peaceful platies
  • Swordtails
  • Mollies
  • Guppies
  • Tetras
  • Rasboras
  • Corydoras catfish
  • Peaceful loaches
  • Dwarf gouramis

Avoid keeping Mickey fish with large aggressive species that may view them as food. Do not house them with fin-nippers like tiger barbs.

Mickey Fish Care Guide

Caring for Mickey Mouse fish is relatively straightforward. Here are some key care guidelines for Mickey fish:

Tank Size

Mickey Mouse platies need at least a 10 gallon aquarium, but a 20 gallon tank is ideal. This gives them adequate swimming space. For each additional Mickey fish, provide 2-3 extra gallons of tank space.

Water Conditions

Use a heater and thermometer to maintain water temperature between 70-82°F. Mickey fish prefer soft to moderately hard water with a pH of 7.0-8.0. Test water regularly and perform partial water changes as needed to keep nitrate levels low.

Decorations and Plants

Mickey fish enjoy planted tanks with lots of hiding spots. Provide plenty of live plants like java fern, anubias, swords, and crypts. Driftwood, rocks, and cave decorations also help them feel secure. Gravel substrate works well.

Tankmates

Select peaceful schooling fish like tetras, rasboras, danios, and small barbs as tankmates. Bottom dwelling fish like cory cats and loaches also make good companions. Introduce any new fish gradually and monitor all inhabitants for aggression.

Feeding

Mickey Mouse fish are omnivores that need both plant and animal matter. Feed a quality flake or pellet along with supplements like:

  • Live or frozen brine shrimp
  • Bloodworms
  • Daphnia
  • Mosquito larvae
  • Vegetables like spinach or zucchini

Feed in small portions 2-3 times per day and remove any uneaten food to keep water clean.

Breeding Mickey Mouse Fish

Breeding Mickey Mouse platies is fairly easy compared to other fish. Here is an overview of the breeding process:

Sexing

Males are generally smaller and more slender than females. Males also have a gonopodium anal fin used for breeding. Females appear wider bodied, especially when laden with eggs.

Spawning

Mickey fish reach sexual maturity around 5-6 months old. They breed through internal fertilization rather than egg scattering. The male uses his gonopodium to fertilize the female’s eggs as she releases them. She can store sperm to fertilize multiple batches of eggs.

Fry Care

Mickey Mouse platy fry are born live and fully-formed. They do not require any specialty care. Feed them infusoria or powdered fry food several times a day. Mickey fish can produce 20-60 fry per month under ideal conditions.

Common Mickey Mouse Fish Diseases

Mickey fish are fairly hardy, but can be susceptible to some common tropical fish diseases. Quarantine and treat any new fish before adding them to your Mickey tank. Some potential issues include:

Ich

Also called white spot disease, ich causes tiny white dots on fins and bodies. It is highly contagious and spreads rapidly in tanks. Treat with medications containing malachite green or formaldehyde. Raise tank temperature to 85°F.

Fin Rot

Fin rot presents itself as frayed, red-tipped fins. It is caused by bacteria and opportunistic fungi. Improve water quality and use antibiotics or antifungal treatments as needed. Separate infected fish.

Flukes

These parasitic flatworms attach to fins and bodies and feed on mucus, tissue, and blood. They can cause flashing, cloudy eyes, and labored breathing. Use anti-parasitic medications to kill the flukes.

Dropsy

Dropsy causes bloating, protruding eyes, and raised scales. It is usually indicative of an internal bacterial infection. Treat with broad spectrum antibiotics and Epsom salt baths. Dropsy is difficult to cure and often fatal.

Swim Bladder Disorder

A compromised swim bladder causes Mickey fish to float or sink. This is often the result of constipation. Treat with Epsom salts and feed frozen peas to relieve blockages. Adjust water temperature and parameters.

Purchasing Healthy Mickey Mouse Fish

Here are some tips for selecting healthy Mickey Mouse platies when buying:

  • Choose an established, reputable fish store
  • Pick active fish with intact fins and bright colors
  • Avoid specimens resting on tank bottom or gasping at surface
  • Watch for signs of disease like spots, fuzz, or worms
  • Select fish raised locally when possible
  • Ask about recent shipments and quarantine procedures
  • Buy juveniles around 1 inch long for best acclimation
  • Introduce new fish gradually to avoid stress

Quarantine new Mickey fish for 2-4 weeks before adding to community tank. Feed a varied diet and maintain excellent water quality for healthy, vibrant Mickey Mouse platies.
