Some betta fish actually prefer dim lighting or even complete darkness. If you’re keeping your betta in a tank with bright light, you may want to consider adding some floating plants or other objects that can provide shade.

Do Betta Fish Glow in Blacklight?

Betta fish have an impressive ability to absorb light and then re-emit it as a different color. This means that they can appear to “glow” in black light. 

While this may be a cool trick, it’s important to remember that bettas are sensitive to light and should not be kept in an environment with bright lights or direct sunlight for an extended period of time. 

If you’re interested in seeing your betta’s “glow,” try turning off the lights in your room and turning on a blacklight. You may be amazed at what you see!

Can You Leave Black Light on All Night for Betta Fish Tank?

You can leave black light on all night for the betta fish tank. This is because bettas are naturally diurnal creatures and prefer to sleep in the dark, just like humans. 

Therefore, by providing them with a black light, you are simulating their natural environment and helping them to feel more comfortable. 

Black light is also known to help improve betta fish health and growth. So not only will your betta appreciate it, but it can actually be beneficial for them!

The best way to ensure your fish get the light they need is to use an automatic timer. This will simultaneously turn the lights on and off every day, so your fish can stick to their natural sleep cycle. 

So go ahead and try it – your bettas will thank you!
