The rainbow gravel looks stunning in my betta tank. It’s easy to work with and the colour is vibrant without being too flashy. I rinsed it well before adding it, and my fish seem unaffected. A great addition to any small aquarium.

I used this gravel in my terrarium and it adds a nice visual appeal. It’s stable and doesn’t shift easily. The only thing is it’s a bit dusty when first unpacked, so rinsing is necessary.

The rainbow effect is beautiful and makes my aquarium look more natural. It’s a good value for the quality and colour range. My fish haven’t shown any signs of stress after a few weeks.
