Review on 12-Piece Plastic Egg Crate Aquarium Fish Tank Divider – Bottom Tray Grid Isolation Board Partition Net Pane Separator for Mixed Breeding, Light Diffuser – Includes 15 Sucker Clips Suction Cups – Black by Shari Smith

Bought this for my 75 gallon grow tank. 6 pieces together, so I had to shorten them a bit. Spacing seems decent, it's soft plastic so was easy to trim with wire cutters. It's strong enough to hold my small 3 inch Oscars alone, but I don't think it will hold up to adults. It has a very strong smell. I'm not sure if it's a chemical smell or a moldy smell. While it's a bit tricky to put the pieces together, they come with a bit of pressure. I could do it myself. The suction cups also make a decent impression. All in all a good temporary separator until my fish move to their larger tanks.
