Amtra 3-in-1 floating spawning box with lid, 12 x 6 cm
This small floating breeding box measuring 12 x 6 cm, with a lid and a removable slotted divider, sits in the aquarium water.
It is used for the birth of a livebearing female, for rearing fry and for isolating a small fish.
The summary
- What you receive: a 12 x 6 cm breeding box, its lid and its removable slotted divider.
- How it protects the brood: the fry pass beneath the divider, out of the female's reach.
- Its three uses: a livebearer giving birth, rearing the fry, setting a small fish apart.
- The duration that matters: a female stays inside only for as long as it takes to give birth.
- The lid: it stops a stressed fish from jumping out of the breeding box.
- Shipping: small, light parcel, easily combined with your order.
Small floating tank for a birth, a nursery or isolating a fish
The Amtra 3-in-1 floating breeding trap, 12 x 6 cm with lid, is used for the birthing of a livebearing female, for rearing fry and for isolating a small fish, without a second aquarium. Its removable slotted divider lets the fry pass beneath the female, out of her reach, and the lid stops a stressed fish from jumping out.
This small tank floats in your aquarium and sits in its water, so the isolated fish keeps the same temperature and the same water parameters as the rest of the tank, the ones monitored with a 6-in-1 water test kit. It serves as a birthing trap for a livebearer female, a nursery for fry and an isolation tank for a small fish, with no need to set up a second aquarium.
🍼 A livebearer giving birth
In guppies, platies and mollies, the female gives birth to fully formed fry, which the other fish in the tank, and the mother herself, readily eat. The slotted breeding trap solves this problem: the female stays in the upper section, while the fry pass through the slots into the compartment below, where she cannot follow them. Install it when her belly is very rounded, but not days in advance, because a prolonged stay in such a small volume stresses her. As soon as the brood is complete, put her back in the aquarium.
Spawning site
The divider is in place, the female stays above and the fry pass through underneath.
Nursery
Once the divider is removed, the fry grow up sheltered from the adults.
Isolation
A small fish that is being chased or kept under observation stays safe under the closed lid.
Moving the female without damaging her fins
A female about to give birth copes badly with being chased around the whole tank. The 8 cm fine-mesh net guides her gently to the breeding box, then brings her back to the aquarium after the birth. Its tight mesh also holds a fry without hurting it, should you need to move one.
Never give a treatment in the spawning tank
The breeding box shares the aquarium water through its side grilles: any medicine poured into it spreads straight away throughout the whole tank. To treat a sick fish, set up a separate quarantine tank.
🔒 Isolating a fish on its own
The third use is the most everyday one: setting aside a small fish that is being chased, a newcomer being bullied, or an individual whose condition you want to observe closely for 2 or 3 days. The box stays in the shared water, so nothing changes for the fish except peace and quiet, and the lid stops it from jumping, which a stressed fish readily does. The volume only suits small species: an adult goldfish or a pond fish has no place in it.
🧽 Installation and maintenance
Place your breeding box against the glass, in an area where the water circulates gently, so that the side grilles renew the water in the compartment without creating a current that bothers the fry. Feed your fry in very small quantities, for example with a crumbled fine granule food for guppies, because whatever is not eaten decomposes on the spot in a small volume. Between uses, take off the lid and the divider, then rinse everything in clean water, without detergent, using a soft brush for the slots.
