Review on 🌳 Hollow Tree Trunk Aquarium Ornament for Fish Tank - Ideal Betta Hideout and Reptile Shelter with Cave for Lizards, Turtles, and Amphibians by Josh Zepeda

I've seen people saying similar things about other products and I was wondering how you can know that an aquarium decoration has killed a fish. So I cleaned it thoroughly, added it to my aquarium and started losing fish. I immediately took it off and cooked it. After it cooled and I rinsed it out, I put it back in the tank. Again my fish started dying WTF. It went in the trash and I bought another at a reputable fish store. Rinsed again and put in the tank. Everything is fine and the catfish are sleeping in the new one. You never know for sure, but I wouldn't risk it if you love your fish. The replacement came from Zoo Med. Good luck!
