Review on CNZ 11.5-Inch Wall Mounted Acrylic Fish Bowl: Securely Display and Enhance Your Fish in Style by Monica Satchell

Not quite full. Also use a screw in the wall. It took me about 2 weeks to hang it on the included nail, then the nail fell out because it's so short and the whole thing fell on the floor and broke. I had screws, screws could be used, but the nail didn't work for me for long. Everything is fine with the fish, it was not in the aquarium when cleaning. And he's in a bigger aquarium now. So do not worry. Otherwise I LOVE this tank. Easy to clean, enough space for a beta and nice setup. No claims on the actual tank. Please use a screw and screw it into the wall. For the safety of your fish (if you use it for this purpose).
