Product Overview
This floating fish breeder box separates fry from adults and keeps vulnerable fish safe. The kit pairs a 3mm mesh inner box with a 0.3mm mesh outer box, each fitted with a suspension ring. Two baby fish feeders come included. It suits keepers hatching guppies, bettas, or clownfish.
Both boxes hang over the tank rim rather than sinking, which the maker says prevents fry from being eaten. Combined, the two boxes handle hatching, isolating biting fish, housing sick fish, or acclimating new arrivals.
Score Breakdown
This verdict is based on the manufacturer's stated specifications, the current Amazon listing and its product images, the confirmed materials and design, real buyer ratings, and our research into the product category. Scores are consistent editorial judgments, not laboratory measurements, and we did not receive a paid sample.
Key Features
3mm inner and 0.3mm outer mesh give two layers of protection.
Each box hangs over the rim to avoid sinking into the tank.
Fine outer mesh keeps tiny fry from escaping to larger fish.
Two 6.1 inch feeders handle yolk feeding and cleanup.
Doubles for isolation, sick fish, or acclimating new arrivals.
Design and Build Quality
The kit lists two nesting boxes. The inner box uses 3mm mesh, measuring 3.31 inches in diameter and 4.64 inches in height. The outer box uses finer 0.3mm mesh, at 3.66 inches diameter and 5.61 inches height.
Each box carries a suspension ring so it floats over the tank rim. That design, per the maker, stops the box sinking and keeps fry out of reach of the mother fish.
Two 6.1 inch baby fish feeders round out the set. The listing says they suck up melted egg yolk to feed fry, and can also clear feces and leftover food to keep the box clean.
Performance in Everyday Use
The dual-mesh approach targets two problems. The 3mm inner mesh separates a mother from her fry, while the 0.3mm outer mesh keeps tiny fry from slipping out and getting eaten by larger tank mates.
Beyond breeding, owners can isolate fish that nip each other, house a sick fish, or acclimate new arrivals. That flexibility makes the set useful past a single spawning.
Honest limits apply. Dimensions and uses come from the listing, not our testing. The stated 3.31 to 5.61 inch sizes suit small fry and compact species, so very large fish will not fit comfortably.

Alternatives Worth a Look
This breeder box set solves a common tank problem in a practical way. Pairing a 3mm inner mesh with a 0.3mm outer mesh gives you two levels of protection, keeping fry away from the mother and out of reach of larger fish. Floating suspension rings stop the boxes sinking, and two feeders help with yolk feeding and cleanup. Beyond breeding, it works for isolating nippy fish, housing a sick one, or acclimating new arrivals. The compact 3.31 to 5.61 inch sizing suits small species and fry rather than large fish. All dimensions come from the listing rather than our own measurement. For guppy, betta, or clownfish keepers, it reads as a versatile, sensible buy.
Frequently Asked Questions
How does this fish breeder box protect baby fish?
It uses two mesh sizes. The 3mm inner box separates the mother from her fry so she cannot eat them. The finer 0.3mm outer box keeps tiny fry from slipping out and being eaten by larger fish. Both boxes float on suspension rings so they stay in place near the surface.
What are the breeder box dimensions?
The inner 3mm mesh box measures 3.31 inches in diameter and 4.64 inches in height. The outer 0.3mm mesh box is 3.66 inches in diameter and 5.61 inches in height. Two 6.1 inch feeders are included. These figures come from the maker's listing and suit small fry and compact species.
Can the box be used for anything besides breeding?
Yes. The maker lists several uses. You can isolate fish that nip each other, house a sick fish for recovery, or use it as an acclimation box for new arrivals. Combining the two boxes gives you flexibility for hatching and general tank separation.
What are the included feeders for?
The two 6.1 inch feeders serve two roles. They suck up melted egg yolk so you can feed fry directly. They also help clean the box by removing fish feces and excess food, which keeps the water inside the breeder box clean for the young fish.
Which fish species suit this breeder box?
The listing names guppies, baby bettas, and saltwater clownfish among suitable species. The compact sizing works best for fry and small fish. Larger adult fish will not fit comfortably, so match the box to small species or young fish that need separation.
