Review on Pawfly 10-20 Pack Suction Cups and Adjustable Zip Ties: Efficient Aquarium Moss Binding and Shrimp Nest Dodging by Jeremy Taylor

They're great for a variety of uses! I have axolotl and no substrate as they tend to eat it. So I used them for artificial plants in the aquarium. I love that you can stick them anywhere which gives you more creativity when placing plants! I have some "hanging" plants on the side wall and the Axia love to hold on to them and swim. They have BIG suction and haven't moved since I put them on almost two months ago. Highly recommended!
