If your Betta fish looks swollen, bloated, or has raised scales that look like a pinecone, you’re likely dealing with a serious condition called dropsy.
This guide will answer the exact question many owners search: “Why is my betta fish bloated and pineconing and how do I treat it?”
What Is Dropsy in Betta Fish?
Dropsy isn’t a disease itself—it’s a symptom of internal organ failure, usually caused by a bacterial infection. It causes fluid buildup inside the body, leading to that distinct swollen, pinecone appearance.
Signs of Dropsy in Betta Fish
If you’re searching things like “why is my betta fish swollen and scales sticking out”, look for these symptoms:
- Bloated or swollen belly
- Scales sticking out (pineconing)
- Lethargy and not moving much
- Loss of appetite
- Pale or faded colour
- Bulging eyes (sometimes)
Pineconing is the most serious warning sign.
For earlier warning signs before this stage, read early signs of dropsy in betta fish.
What Causes Dropsy in Betta Fish?
Dropsy is usually the result of long-term stress or internal infection rather than a single cause.
Main causes include:
- Poor water quality
- Bacterial infection
- Stress (small tanks, no heater, sudden changes)
- Overfeeding
How to Treat Dropsy in Betta Fish at Home
If you’re searching “how to cure dropsy in betta fish fast”, here’s what you can do.
Start by isolating your Betta fish in a quarantine tank with clean, warm water. Keeping conditions stable is critical during treatment.
You should also perform regular water changes, maintain a temperature of 26–28°C, and reduce stress as much as possible. In some cases, aquarium salt and antibacterial treatment may be used carefully to support recovery.

- Early stage: possible recovery
