Explain this weird anomaly in my tank please...

[Rocky998]

So here I was sitting in front of my tank when all of a sudden I see a blue light coming from a "cave" area in my tank... I thought: "I know I haven't bought anything that glows".
So I look in and my sand particles are glowing blue. This is a FRESHWATER aquarium. Weird stuff like this isn't supposed to happen
I have a photo but my camera for some reason didn't want to clear on the particles of sand glowing...
I have an explanation in my mind that sounds rational.
Prisms. The colored LED light doesn't shine directly on that sand in the cave bit it's does shine on another open section very very close to it which could be reflecting through the sand particles as blue...

Kinda thought that would be the first response I'd get

May we see a picture of the whole tank?
Also, how do you react with anything but a like?

If you are on a computer, just let your mouse rest on the like button. If you are on a phone, hold the button down for a moment.

Oops, didn't see that question... It was either just added or it didn't load in for me
Yes, just do what Morganna said.

Based on things I've seen here, the prism idea makes sense.

Either that, or the blue eye of Sauron's cousin Brad.

Any light shining directly on that part? Must be reflecting
