Review on POPETPOP Aquarium Divider Isolation Breeding by Christine Rowe

I bought a separator because I wanted to put my red betta in this 20 gallon aquarium. In the beginning it worked fine. I went out 2 hours, came back and found the red rooster crossed. The red is big and aggressive. Blue is smaller and calmer, so she was hit very badly. I'm sad because their beautiful fins are damaged. Luckily I kept Red's house so I just brought her back. Now Red is very excited in her 1 gallon tank, swimming and banging on the glass. The blue that used to be playful and energetic now sits on gravel or hides in barrels. I bought two splitters (I was going to buy a 50 gallon tank) but will be returning both and waiting for a refund. This divider is suitable for big fish. But if you have female bettas I do NOT recommend this product.
