Decorating a fishbowl or tank with little branches and leaves to make fish feel at home is no strange thing. In fact, it acts as a sort of souvenir of their old home and their natural habitat. But in your haste to decorate your fish’s home, you might bring in something that can kill or harm them. 

While pine needles may appear delicate and pretty, they are very harmful, if not poisonous for your fish.


What Are Pine Needles?

Pine needles are the “leaves” of a pine tree that get shed and blown into the wind. Eventually, they land on the ground. These needles act as a form of reproduction for the pine tree by transferring to the ground. Pine needles are very thin, sharp, and coarse.

They may even end up pricking your finger if you are not careful enough while picking them up.

If you have a pond next to a pine tree or have picked some pine needles up thinking they look pretty, you may end up bringing in just the thing that will become the cause of your fish’s death.

While they may be versatile in use and nature and are quite beneficial if used correctly, they are not something you feed your fish with or use to decorate its home.


Why Are They Harmful To Fish?

While pine needles aren’t directly poisonous for fish, they still can be harmful to them in the water. Pine needles are technically leaves. So, if you have a pine tree near your pond or have put some pine needles in your fish’s bowl, they will decompose after a while.

Due to decomposing, it will become a smelly and disgusting mess that you’ll need to clean up. Additionally, the decomposing will cause the pH levels of your fish’s water to change. That can be a significant cause of your fish dying.

The decomposing will turn the water a slightly green color, and that too can affect your fish’s health. If the pH level of your water is high, it means that it’s too acidic for fish to survive.

Not only that, your fish can accidentally swallow the pine needles. As a result, they may get stuck in their throat and intestines. That can even cause their death if not removed on time.

Pine needles do not act as a poisonous threat directly, but they can become extremely harmful. While they do not act as a toxic substance, the decomposition, the pH build-up, the danger of swallowing, and them eventually destroying the water’s ecosystem are reasons enough to stay clear of them.


How To Prevent Pine Needles From Harming Fish

The two basic ways to prevent pine needles from harming the fish are catch netting and manual skimming. The cheapest method is to do it yourself, aka manual skimming. Just take some time out during your afternoon and step inside your pond with some grip slippers and a garbage bag. 

Carefully maneuver through the fish and collect the fallen pine needles.

The second-best option is installing a mesh catch netting on your pond so that the needles fall on top of it without getting in the water and harming the fish. 

Make sure it is made from a material that the fish can breathe through.
