Great product for separating fish without disrupting water flow. Easy to install and fits well in my 20-gallon tank. My baby fish now have a safe space to grow.

Works well for keeping aggressive fish separate from peaceful ones. The water circulation remains smooth, and I didn’t notice any issues with filtration.
Michael Morrison –
I used it to create a breeding zone for my guppies. The divider is sturdy and doesn’t block the filter. My fish seem more comfortable now.
