The BioBubble Wonder Bubble Tunnel Kit is an interesting concept that makes for a cool conversation piece, but might have a few small drawbacks. The concept is really cool, there is a tube with water that allows small fish to swim up and appear out of the water.
The Wonder Bubble Tunnel isn’t that big and is marketed towards casual freshwater Betta owners and other small fish. There is much debate about keeping Bettas in small enclosures, and there are practical arguments in favor of that. But this could be a cool little setup for guppies, mollies or other smaller fish.
The main part of the Bubble Tunnel is the semi-spherical bowl holding the majority of the water. The tunnel itself is a curved plastic tube with a bubble in the middle. You fill the tunnel with water, cap the ends, submerse in the main bowl, and carefully pull the caps off to connect the tunnel to the bowl.
The whole kit holds around 1.5 gallons of water and measures in around 12 x 14 x 14 in. While it looks pretty cool, there are some mixed reviews online. Some people absolutely love it and give it a full 5 stars, but others point out things like the tube and bold being made from thin plastic, the tube not being truly secured to the tank and other issues.
If you’re looking for something cool and different for under $50, this might be right up your alley. You can grab one of these online for around $40.
