Pocket BotanistCheck these first
- Check the water pH level with a test kit.
- Look for tiny prey swimming in the water.
- Ensure the plant is not being crowded by algae.
Likely causes
Water chemistry imbalance
Most likelyHow to tell: The plant looks limp and loses its buoyancy. This happens when the water pH is too high or contains too many dissolved minerals.
What to do: Test your water pH and aim for a range of 5.5 to 6.5. Use peat moss or specialized aquarium additives to lower the pH if it is too alkaline.
Lack of food
PossibleHow to tell: The plant looks thin and lacks the energy to hold its shape. Without small aquatic insects, the plant cannot produce enough energy to grow.
What to do: Introduce small live prey like daphnia or mosquito larvae into the water. If you cannot find live food, ensure the plant is in a location where it can naturally catch small organisms.
When to worry
If the plant sinks to the bottom and stays there, it is likely dying. It is normal for the plant to look slightly less perky at night.
Stopping it coming back
Maintain a slightly acidic water environment and ensure the plant has access to tiny prey.

Questions people ask
- Can I feed it fish food?
- No, fish food will rot the water and kill the plant. Only use live, tiny aquatic organisms.
- Is my plant dead if it sinks?
- Not necessarily, but it is a sign of poor health. Check your water quality immediately to see if you can revive it.
