  • Worth the money
The media could not be loaded. Oh this is so worth the money. If you have a fish tank, then you need one! Set up was easy and it stays straight and level. Must use all 3 prung scres to hold in place.

It's super cool I thought it'd be a little bigger but still cool

  • Innovative tank enhancement!
Super easy to install, and a great way to create additional space in a small tank and/or a conversation piece for your display tank.

  • You get what you pay for.....
When I opened the package, there was only 2 clips in there when it showed there was 3. The clips wouldn't stay down when I tried to put the attachment on it and then would pop off the aquarium. If you are thinking about getting one of these, remember you get what you pay for. Spend a little more money and get something you will be able to enjoy. ... show more

  • It doesn't fit the edge of a standard fish tank
It's very small, which I know measurements are provided, but I wouldn't recommend for fish larger than small tetras. Also, if you have a fish tank with any edging/plastic rimming, you can't use this. It won't fit. It can only be used for rimless tanks. I have a small one luckily I could use this on. Other than that, the instructions are easy enought to use and it works like it's supposed to. ... show more
