Jardin Plastic Frame Net Fry Hatchery Breeder for Aquarium, White

It was pretty easy to assemble, the netting goes right over everything except the sucker parts. the sucker parts though you have to really push to get them on, then when you get them on you have to press them onto the tank really well or else the hatchery will sink and your frog might get in and eat all your baby fish... then when its time to get out the remaining survivors of the frog attack its really difficult because the suckers wont detatch. Overall though, its a pretty good product and if you lower your water level a little then you'll be fine.
