Review on 🐠 Penn-Plax Pro Balance 14-Day Vacation Feeding Blocks Fish Shape (Set of 2) - Optimal SEO-friendly Product Name by Jose Strong

I tried it out before the holiday and a week after I put it in my 10 gallon 78F tank it was still in the same condition it was right after the packing. It looked like a hard piece of plaster. I took it out a week after it was in the water to break it in half to see if there was food for the fish inside. I couldn't break it and used a screwdriver instead of a chisel and hammer to break it. There was NOTHING in it that could pass as fish food. It was a hard, plaster-like material. NO FISH PRODUCTS.
