Breeder Net vs a Separate Grow-Out Tank
In-tank breeder net vs a separate grow-out tank for fry: water quality, feeding, growth rate, predation and which to use.
The short version
A breeder net keeps fry safe from being eaten while sharing the parent tank's stable water, which is convenient and cramped. A grow-out tank gives room, cleaner water and controlled feeding, which is what actually produces well-grown fish. Use the net for the first days and for rescues; use a grow-out tank if you intend to raise a spawn properly.

Choose the Mesh Breeder Net, 2 Pack if…
You need somewhere immediate for a surprise batch of fry or an injured fish. Nets are cheap, instant and fine for a short period, provided you accept that fry crowded in a net grow slowly and unevenly.

Choose the Tetra LED 10 Gallon Complete Kit if…
You want the fry to reach a decent size. Growth is driven by space, frequent small feedings and clean water, and all three are difficult in a net hanging in a stocked tank. Frequent partial water changes matter more here than in any other tank.

Frequently Asked Questions
What do I feed fry?
Something small enough to fit their mouths: infusoria or liquid fry food at first for tiny fry, then baby brine shrimp and crushed flake as they grow. Most fry losses come from food being too large rather than too little.
Why are my fry growing at different rates?
Competition and crowding. Larger fry outcompete smaller ones and in some species will eat them. Sorting by size into separate containers is standard practice for anyone raising a spawn seriously.
How often should I change water in a grow-out tank?
More often than a display tank, frequently and in small amounts. Growth hormone build-up and waste both stunt fry, and clean water is the single biggest factor in how they turn out.
