Review on Petzilla In-Tank Fish Tank Breeder Box - Aquarium Breeding Incubator for Small Fish Hatchery, Acrylic Divider for Shrimp, Clownfish, Aggressive & Injured Fish by Rose Washington

Bought for use with guppies. I had a little trouble with the divider separating the top from the bottom because it kept popping up I fixed it by putting a bead in a "V" that weighed it down and held it in place.I placed a pregnant female guppy in the upper chamber and was surprised to find two days later that the babies were chased all over the tank there was none in the breed box, upon closer inspection of the box I noticed that while the side slots are the perfect size the bottom slots are too big I would not be able to use this box for breeding Guppies without significant modification.
