Common Molly Fish Diseases
Molly fish are popular aquarium pets. They can get sick if their environment is not clean. Knowing common diseases helps keep them healthy.
Fish diseases show signs like spots, frayed fins, or strange swimming. Early care can save your fish.
Ichthyophthirius (ich)
Ich is a parasite that causes white spots on fish skin and fins. It makes fish scratch against objects and breathe fast. Cold water and crowded tanks increase risk.
- Keep water clean and warm
- Quarantine new fish before adding
- Use ich treatment if spots appear
Fin Rot
Fin rot causes torn and discolored fins. Bacteria or poor water quality cause this disease. Stress and injury make fish more vulnerable.
| Prevention | Treatment |
| Change water regularly | Antibacterial medication |
| Avoid overcrowding | Remove affected fish if needed |
| Keep filter clean | Improve water conditions |
Velvet Disease
Velvet disease covers fish with a fine yellow or gold dust. It causes fish to hide, lose appetite, and have breathing problems. Parasites cause this disease.
Prevention tips include:
- Keep tank dark during treatment
- Maintain good water quality
- Isolate sick fish quickly
- Use copper-based medications as needed
Swim Bladder Disorder
Swim bladder disorder affects fish balance. Fish may float sideways or sink. It can come from poor diet, constipation, or infections.
- Feed a varied, balanced diet
- Avoid overfeeding
- Use pea as a laxative for constipation
- Keep water clean and stable
Signs Of Disease In Mollies
Mollies are popular freshwater fish that can get sick like other pets. Knowing the signs of disease helps you act fast.
Spotting illness early keeps your mollies healthy and happy. Watch for changes in their behavior and body.
Behavioral Changes
Sick mollies often act differently than usual. They may hide or swim less than normal.
Look for signs like loss of appetite or slow movements. These changes can mean illness.
- Less active or lethargic swimming
- Hiding in corners or behind plants
- Not eating or rejecting food
- Gasping at the water surface
- Scratching against objects
Physical Symptoms
Physical signs of disease include changes in color or spots on the fish’s body. Check fins and scales closely.
Look for swelling, redness, or damaged fins. These symptoms often show infection or injury.
- White spots or patches on skin
- Red or inflamed areas
- Clamped or torn fins
- Swollen belly or eyes
- Excess mucus or slime
Maintaining Water Quality
Good water quality keeps molly fish healthy and disease-free. Clean water lowers stress and stops bacteria growth.
Check water often and keep it stable. This helps molly fish live longer and stay strong.
Regular Water Testing
Test water weekly to check pH, ammonia, nitrite, and nitrate levels. These affect fish health.
Use simple test kits from pet stores. Record results to spot changes early and fix problems fast.
- Keep pH between 7.5 and 8.5
- Ammonia and nitrite must be zero
- Nitrate should stay below 20 ppm
Proper Filtration
Use a good filter to clean water and remove waste. Filters stop harmful bacteria from building up.
Choose filters that fit your tank size. Clean or replace filter parts regularly to keep water clear.
- Mechanical filters trap debris
- Biological filters help break down waste
- Chemical filters remove toxins
Water Temperature Control
Keep water temperature steady between 72°F and 78°F. Sudden changes stress molly fish and cause illness.
Use a reliable heater and thermometer. Check temperature daily and adjust heater if needed.
Feeding Practices
Proper feeding helps keep Molly fish healthy. Good food and the right amount stop many diseases.
Feeding habits affect water quality and fish immunity. Careful feeding keeps the tank clean and fish strong.
Balanced Diet
Molly fish need a mix of foods to stay healthy. Feed them flakes, pellets, and fresh vegetables.
A balanced diet gives vitamins, minerals, and proteins. These nutrients help fight diseases.
- Use high-quality flakes or pellets as main food
- Add blanched spinach or zucchini for vitamins
- Include live or frozen foods like brine shrimp for protein
- Change food types to give variety
Avoiding Overfeeding
Overfeeding causes leftover food to pollute water. Dirty water leads to fish sickness.
Feed small amounts that fish eat in 2-3 minutes. Remove extra food after feeding.
- Feed 2-3 times a day in small portions
- Watch fish eat and stop when they are full
- Clean uneaten food from the tank
- Adjust feeding if fish act lazy or water looks cloudy
Tank Setup And Maintenance
Proper tank setup and maintenance help prevent diseases in molly fish. A healthy environment keeps your fish safe and happy.
This guide covers how to provide adequate space, maintain a cleaning schedule, and choose suitable plants and decorations.
Adequate Space
Molly fish need enough room to swim freely and reduce stress. Overcrowding can cause illness and poor water quality.
- Provide at least 10 gallons of water per molly fish
- Use a wide tank to allow horizontal swimming
- Avoid keeping too many fish in one tank
- Separate sick fish to prevent spreading disease
Cleaning Schedule
Regular cleaning keeps the tank water safe and free from harmful bacteria. It also helps remove waste and leftover food.
| Cleaning Task | Frequency | Details |
| Water Change | Weekly | Replace 25% to 30% of the water |
| Filter Check | Every 2 Weeks | Clean or replace filter media if needed |
| Gravel Vacuuming | Weekly | Remove debris and uneaten food from substrate |
| Glass Cleaning | Weekly | Wipe algae from tank walls |
Suitable Plants And Decorations
Choosing the right plants and decorations can reduce stress and improve molly fish health. Some plants also help keep water clean.
- Use live plants like Java moss, Anubias, or Hornwort
- Avoid sharp or rough decorations that can injure fish
- Provide hiding spots with caves or smooth rocks
- Keep plants trimmed to prevent overcrowding

Quarantine New Fish
Quarantining new fish is important to prevent diseases. It helps protect your existing molly fish.
New fish can carry diseases. Quarantine keeps them separate until you know they are healthy.

Watch them closely for any signs of sickness. Use a separate tank to avoid spreading any diseases.
- Check for unusual spots or discoloration

| Factor | Ideal Range |
| Water Temperature | 24-28°C (75-82°F) |
| pH Level | 7.5-8.5 |
