Bests & Worsts Reviews from Amazon

I ordered the small but was not expecting it to be super small. It will fit in the palm of your hand. Even thought it was really small I still used it and thought it could work. But once I put the fry in the tiny box there were holes around the bottom and the fry just swam right out. The holes are way to large even the eggs fall through the holes. The lid that goes on the top does not fit snugly if you put it even with the water line. The lid will float up and off allowing larger fish inside and the fry outside. The suction cups hold pretty good, and stays stuck on the side of the tank. If you lift the tiny box out of the water make sure there are no fish inside because all of the water drains out the bottom holes so you have to keep the little box submerged somewhat in order to keep water inside. Even though I measured the size small was super small. I must have measured wrong. It would be fine for small fish like neons or small fish like that. I have zebra fish (danios) the box was actually to small for them to turn around in. The first photo is full view of my 20 gal tank with the little box in the middle at the top. The other photo is zoomed in. Not happy with the little box at all. Its cheaper to just keep it. My first order never came and I had to get a refund and reorder. The package did arrive undamaged and item had no cracks.
