Review on 🐠 Penn-Plax Deco-Replicas Granite Aquarium Ornaments - Authentic Stone Appearance - Fish Tank Safe for Freshwater and Saltwater - Ideal for Territorial Fish by Samantha Carlisle

Would give 5 stars but as ALL said they are ROUGH. I didn't have sandpaper, so I used kitchen utensils with flat ends and round tips to go over it like I would carve. Back and forth until smooth. Waste of time and chaos wrought. I was skeptical, but after a while the fish liked them and are very happy. Also, even though I had a swim bladder, I bought Rocky from an unnamed "ko" because I showed them and they weren't interested. So 2 is better anyway. He was in trouble, and I remembered the trick I'd done before: I put them in a small cup with minimal effort to get air, but was still able to move freely. I put a small round object, a small pestle, that I had in it and it got to its feet with no problem, swam and after a few days of rest began to eat. When he could stand up on his own, I took out the center piece. Then, a few days later, a bowl larger than his new home. That's why his name is Rocky. He did it!
