BioBubble 3D Background Coral Reef 20 gallons 24" x 12"

I had an old fish tank with a mirror backing - stressful for bettas! This made it super easy to cover the mirror without having to do any scraping or painting whatsoever. Just trim to fit your tank and suction cup it into place! It looks great too! Very happy with it!

Beautiful, really adds depth to my tank!
I have a 28 gallon freshwater cube tank with built in filter compartment in the back, so the back of the tank was plain black. This goes inside the tank, attached either with the suction cups, or super glue gel ( harmless to fish), if already set up, like mine was.
Just remove some water, slide bottom between substrate and glass, and attach. The 20 gal. size was more than large enough, had to cut side and top.
Molded, thin, 3D plastic, easy to cut with scissors, and takes up a lot less room in the tank than thick, expensive, foam 3D backgrounds.
Really adds pizzazz with some added nice coral reef decorations.
Who says a freshwater tank shouldn’t look as striking as a saltwater reef tank?

It is almost a perfect fit for my 20 gallon aquarium. With my led light bouncing off the 3d background, it looks awesome.

Love this backround!

Excellent background. Put background on before setting up the tank. Makes the process much easier. I have this background for my 20 gallon glofish tank and it looks magnificent. I do not regret my purchase at all
