Corydoras love to sift! Their little whiskers are super sensitive, so sharp substrate is a big no-no. That's where this Aquarium-Safe Tumbled Gravel comes in. These smooth, rounded pieces are perfect for your Corys to dig through without damaging their delicate barbels. Watching them sift through the substrate is half the fun of owning them, right?
