You’re admiring your vibrant aquarium, watching your beautiful Golden Doubloon Mollies shimmer under the light. Then, your heart skips a beat.

Is she sick? Is she dying? What is that thing?
Take a deep breath. You’ve come to the right place. Here at Aquifarm, we’ve seen it all, and we’re here to help you decipher exactly what’s going on with your fishy friend. The good news is that this “weird thing” is often completely normal and nothing to worry about.
In this complete guide, we promise to walk you through every possibility. We’ll cover the harmless, everyday occurrences like pooping and giving birth, and we’ll also tackle the more serious issues like prolapse and internal parasites. You’ll learn how to tell the difference, what immediate steps to take, and how to create a tank environment where your mollies thrive. Let’s solve this mystery together!
First Things First: Don’t Panic! A Quick Diagnostic Checklist
Before you start rearranging your tank or rushing to the store for medication, let’s play detective. The nature of the “thing” hanging from your molly will tell you almost everything you need to know. Grab a seat in front of your tank and calmly observe.
Ask yourself these simple questions:
- What color is it? Is it brown, reddish, white, clear, or multi-colored?
- What is the texture? Does it look like a string, a fleshy mass, a worm, or something fuzzy?
- How is your molly behaving? Is she swimming and eating normally? Or is she lethargic, hiding, clamped fins, or refusing food?
- Are other fish showing similar signs? This can help determine if it’s an individual issue or a tank-wide problem.
Your answers will point you toward one of the common scenarios below. Remember, observation is your most powerful tool in fishkeeping.
The Most Common (And Harmless) Culprits
More often than not, what you’re seeing is a normal biological process. Mollies are hardy and active fish, and their bodies are busy doing all sorts of things. Here are the two most likely—and completely harmless—causes.
Just Doing Her Business: The Deal with Molly Poop
Yes, the most common “weird thing” is simply poop! It might sound silly, but fish waste can look surprisingly strange to the uninitiated. Before it detaches, a molly’s feces can hang from its vent (the opening where waste is expelled) for a few minutes or even longer.
What to look for:
- Appearance: Normal molly poop should be solid and typically the color of the food they’ve recently eaten. If you feed them brown flakes, the poop will be brown. If you’ve given them green veggies, it might be greenish.
- Behavior: The fish should be acting completely normal. She’ll be swimming, socializing, and eating with her usual gusto.
- Duration: It should detach on its own within an hour or so. If it hangs on for many hours or even days, it could be a sign of constipation, which we’ll cover later.
If what you’re seeing matches this description, relax! Your molly is just fine. This is a perfect example of why a good golden doubloon molly fish female weird thing hanging out care guide starts with simple observation.
Special Delivery! Signs Your Molly is Giving Birth
Golden Doubloon Mollies are livebearers, which means they give birth to free-swimming baby fish (called fry) instead of laying eggs. This process can look a bit strange! If your female molly has been housed with a male, pregnancy is a very likely explanation.
What to look for:
- The Gravid Spot: Look near her anal fin. A pregnant female will develop a dark, prominent spot called a gravid spot. This is the area where the fry are developing, and it gets darker and larger as she nears her due date.
- Body Shape: She will look noticeably plump or “boxy” in the abdomen.
- Behavioral Changes: Right before giving birth, she might become reclusive, hide near the heater or filter intake, or seem a bit agitated.
- The “Thing”: During birth, you might see a tiny, curled-up fry emerging from her vent. Sometimes, a bit of afterbirth or unfertilized egg material can also be expelled, which can look like a clear or yellowish stringy substance.
Witnessing a live birth is one of the most exciting benefits of golden doubloon molly fish female weird thing hanging out in your tank—it means you have a healthy, thriving environment! Don’t worry—these fish are perfect for beginners and are prolific breeders. Just be prepared with a plan for the fry!
When to Worry: A Guide to Common Problems with Golden Doubloon Molly Fish Female Weird Thing Hanging Out
While poop and birth are common, sometimes the “weird thing” is a sign of a health issue. This is where your careful observation pays off. Let’s explore the more serious possibilities in this golden doubloon molly fish female weird thing hanging out guide.
Anal Prolapse: What It Is and What to Do
A prolapse occurs when a part of the fish’s intestines protrudes from the vent. It can be caused by straining due to constipation, giving birth to very large fry, or an internal infection.
What it looks like: A prolapse appears as a pinkish or reddish fleshy mass hanging from the vent. It will not look like a string of poop; it looks like internal tissue that is now on the outside. Your fish will likely seem distressed, may stop eating, and might isolate itself.
What to do:
- Isolate the fish: Immediately move the affected molly to a quarantine or hospital tank with clean, conditioned water. This prevents other fish from picking at the sensitive area.
- Epsom Salt Bath: The best first-line treatment is an Epsom salt (magnesium sulfate) bath. It helps reduce swelling and can allow the tissue to retract. Use 1 tablespoon of pure Epsom salt (no perfumes or additives) per 1-2 gallons of water. Let the fish soak for 15-30 minutes, monitoring her closely.
- Improve Diet: Withhold food for 24-48 hours. Then, offer high-fiber foods like blanched peas (with the skin removed), daphnia, or brine shrimp to ease constipation.
Internal Parasites: The Stringy White Poop Problem
Internal parasites are a common problem in aquarium fish. The most obvious sign is the appearance of their waste.
What it looks like: Instead of solid, colored feces, you’ll see long, thin, stringy, and white or clear poop. It can hang from the fish for a long time. In more severe cases, like with Camallanus worms, you might see small, reddish-brown worms actively wiggling from the fish’s vent. This is a serious condition that requires immediate action.
What to do:
- Confirm the Diagnosis: Observe carefully. Is the poop consistently white and stringy? Does the fish also have a sunken belly or seem lethargic?
- Medicate: If you suspect parasites, you’ll need to treat with a medicated food or water treatment. Products containing Metronidazole or Praziquantel are effective against many internal parasites. For Camallanus worms, you will need a specific dewormer like Fenbendazole or Levamisole.
- Treat the Main Tank: Because parasites are highly contagious, you should treat the entire main tank, not just the single fish.
Your Action Plan: How to Golden Doubloon Molly Fish Female Weird Thing Hanging Out
Okay, you’ve identified the potential issue. Now what? Here are the concrete steps and golden doubloon molly fish female weird thing hanging out tips to follow.
Step 1: Observe and Document
Don’t just rely on memory. Take a clear photo or video with your phone. Note the fish’s behavior, the time of day, and any other symptoms. This information is invaluable if you need to ask for help online or at your local fish store.
Step 2: The Power of a Quarantine Tank
Every serious aquarist should have a small (5-10 gallon) quarantine tank (QT). It’s essential for treating sick fish without medicating your entire display tank and for preventing the spread of disease. A simple QT setup includes a heater and a gentle filter (like a sponge filter).
Step 3: Simple Home Remedies
For issues like constipation or minor prolapse, home remedies are a great, eco-friendly golden doubloon molly fish female weird thing hanging out solution.
- Epsom Salt Baths: As mentioned, this is a go-to for swelling and constipation.
- Dietary Changes: Feed blanched, de-skinned peas once a week as a laxative. Fasting your fish for one day a week can also help clear their digestive systems.
Prevention is the Best Medicine: Golden Doubloon Molly Fish Female Weird Thing Hanging Out Best Practices
The ultimate goal is to prevent these problems from ever happening. A healthy, stress-free fish is far less likely to suffer from prolapse or fall victim to parasites. Following these best practices is the key to a thriving aquarium.
The Foundation: Pristine Water Quality
This is non-negotiable. Poor water quality is the number one cause of stress and disease in fish.
- Cycle Your Tank: Ensure your tank is fully cycled before adding fish.
- Regular Water Changes: Perform a 25-30% water change every week.
- Test Your Water: Regularly test for ammonia, nitrite, and nitrate. Ammonia and nitrite should always be at 0 ppm.
A Balanced Diet for Happy Guts
A varied diet is crucial for digestive health and preventing the blockages that can lead to prolapse.
- High-Quality Flakes/Pellets: Use a high-quality staple food.
- Incorporate Fiber: Offer blanched vegetables like peas, zucchini, or spinach once or twice a week.
- Offer Frozen/Live Foods: Supplement their diet with protein-rich treats like daphnia and brine shrimp. Daphnia, in particular, has a laxative effect and is excellent for digestive health.
Creating a Low-Stress Environment
A stressed fish has a weakened immune system. Creating a calm, sustainable golden doubloon molly fish female weird thing hanging out environment is vital.
- Proper Tank Size: A minimum of a 20-gallon tank is recommended for a small group of mollies.
- Correct Male-to-Female Ratio: Keep at least two to three females for every one male. This spreads out the male’s constant breeding attention and reduces stress on any single female.
- Provide Hiding Spots: Use plants (live or silk) and decorations to create plenty of hiding spots where fish can feel secure.
Frequently Asked Questions About Your Molly’s Health
How long is too long for poop to be hanging from my molly?
While it varies, if a piece of feces is hanging for more than a few hours, it could be a sign of mild constipation. If you see long, stringy, white poop that hangs on for days, you should suspect internal parasites.
Is my golden doubloon molly pregnant or just fat?
Look for the key signs of pregnancy: a boxy, squared-off belly shape (not just a rounded one) and the presence of a dark gravid spot near the anal fin. A molly that is simply overfed will have a more rounded, bloated look all over.
Can a prolapse heal on its own?
A very minor prolapse might retract on its own if the underlying cause (like constipation) is resolved quickly. However, it’s always best to intervene with isolation and an Epsom salt bath to increase the chances of recovery and prevent infection.
What’s the best eco-friendly way to treat minor fish ailments?
The most eco-friendly golden doubloon molly fish female weird thing hanging out approach is always prevention through pristine water and a great diet. For minor issues, using natural treatments like Epsom salt for swelling, garlic-soaked food to boost immunity, and simply maintaining impeccable water quality are fantastic, chemical-free methods.
You’ve Got This!
Seeing a weird thing hanging out of your golden doubloon molly female can be alarming, but now you are armed with the knowledge to diagnose the situation like a pro. In most cases, it’s a simple, natural process. And even when it’s not, you now have a clear action plan to help your fish recover.
By focusing on excellent water quality, a varied diet, and a low-stress environment, you’re not just solving a single problem—you’re building the foundation for a beautiful, healthy aquarium for years to come.
