Ace Seller Aquarium Fish Tank Clear Plastic Breeding Fish Spawn Hatchery Isolation Box

It can obviously be used for a female who will soon have her fry but don' believe that the babies can reach their maturity (or even grow) in such a small motherhood. The fry needs more space. Also, if you leave the female with fry, she may eat them if they did not go in the section that protects them. In my opinion, it is an alternative when we don't have any spare aquarium. Personally, I use it to isolate an injured fish or when they need a little break from some aggressive fishes in the tank.
