Aquarium fry breeder box

Keep newborn fish fry safe inside the tank in a slotted box

Livebearers like guppies and mollies give birth, and the adults eat the fry within hours. This slotted box hangs inside the tank with tank water flowing through every side, keeping the fry safe in their own nursery until they are big enough to join the others. The divider keeps two broods apart.
