Hey aquarium lovers! If you're dealing with baby fish or need to separate aggressive tank mates, these breeder nets are absolute lifesavers. Each set comes with two transparent boxes measuring about 10.3 x 5.9 x 5.9 inches - perfect for protecting fry or isolating fish that need some alone time. The soft polyester net has small enough holes that even the tiniest baby fish can't escape, while the plastic frame keeps everything sturdy. What I love is the six suction cups on each net - they stick securely to your tank walls without any hassle. The transparent design lets you keep an eye on your fish without disturbing them, which is crucial when you're dealing with sensitive baby fish or recovering specimens. Seriously, if you've ever lost baby fish to larger tank mates or watched a bullied fish get stressed, this simple solution can dramatically increase survival rates. They're made from quality materials that hold up well in water, and the package includes everything you need - 2 breeding boxes and 12 suction cups total. Whether you're a serious breeder or just dealing with some fin-nipping issues, these boxes make fish parenting so much easier!
