BREEDING TRAP
a device to prevent the mother and other fishes from eating the newly-born fry in an aquarium. A pregnant livebearer can be placed in a special container within the aquarium, the container confining the female but allowing the fry to swim out through small holes. This type of trap only works where there are no other fishes in the aquarium. An alternative trap allows the fry to enter and seek refuge from the mother and other fishes in a community tank
