Great product for separating fish without disrupting water flow. Easy to install and fits well in my 18-gallon tank. My baby fish now have a safe space while the aggressive ones stay in their own area. Works perfectly as expected.

Installed it in my 20-gallon tank and it’s been working well. The fish seem more relaxed, and I can now monitor breeding without stress. Slight trimming was needed for a perfect fit, but that was easy.

Highly recommend this divider. It’s simple, effective, and doesn’t block water circulation. My community tank now has a peaceful setup with separate zones for different fish types.
