Yet again, a short little clip, simply showing you what the BiOrb Bubble Tube Guard looks like so you can know before you buy.
Some fish like to try a squeeze themselves into the most unlikely places. Just in case one of the fish in your BiOrb aquarium enjoys this behavior, we have a top for the BiOrb bubble tube, which prevents fish from getting in, while still allowing bubbles to get out.
The biorb tube guard slides over the opening of the biorb bubble tube to prevent your fish from swimming down the bubble tube and getting stuck in your filter. The biorb bubble tube guard might just be the difference between life and death for your fish.
