Review on OIIKI Aquarium Divider Isolation Breeding by Michelle Moore

I ordered this aquarium divider because it had good reviews and it shipped within a day. It arrived quickly and was easy to assemble. However, the bars are wide enough for an adult betta to swim through. It also doesn't fit because it's too big, but I wanted to cut it off. I was hoping to get my bettas back in the same tank, but the aggressive bully found its way through the bars right away. It may run down the sides because it doesn't fit the glass perfectly. He can also swim just about anywhere because he's found it fits. The offended can also squeeze through to escape, but they get tired and get stuck a bit. I had to separate them into different tanks again. This is definitely a big fish solution.
