They're at the bottom of our tank so we don't have suction problems. They look rather slim and thin in my opinion. Also, they are short. To be honest, I would like something different. To update. After only a few months they look mouldy/algae covered. The tank is clean, but not this one. We have other aquarium decorations that last longer and don't look like algae. In general I do not recommend.
