To the question “Do a goldfish need light at night?” The answer is yes! Fish have very complex biological systems in their brains. They don’t have eyes, but they can still see.

Fish can’t see colors as we can, but they can detect minor differences in light wavelengths. These differences tell the fish whether it is day or night. Because fish can see the light in their tank, they need light at night. This way, they know whether it is day or night and can adjust their biological clock accordingly.

  • Fluorescent aquarium lamps: These lamps use fluorescent bulbs to produce a bright light.
  • Halogen aquarium lamps: These lamps use halogen bulbs to make a bright, white light.
  • Incandescent aquarium lamps: These lamps use incandescent bulbs to have a soft, warm glow.

First, cut a small hole in the bottom of the bowl or fish tank. This will be where you insert the LED light. Ensure the gap is small enough so the light will be snug. Next, take the transparent plastic sheet and cut it into a circle.

The circle should be larger than the hole you missed at the bowl’s bottom. Hot glue the plastic sheet to the bottom of the bowl, being sure to seal the edges well. Now it’s time to add the goldfish. Gently add them to the bowl one at a time. You can use a small net to help guide them into the bowl if necessary.

Once the fish are in, please turn on the LED light and watch as they swim around in the light. You can see and experiment with different sizes and colors of LED lights to see what looks best. You can also add other decorations to the bowl, such as rocks or plants. Be creative and have fun!
