Was wondering anyone who owns one or has owned one are they burrowers? This newest fella I got is a burrowing machine.

What is being described as burrowing behavior is feeding behavior, they like to sift through gravel substrate to find food buried within it. You will have very clean gravel as a result. A good thing as it prevents a lot of funky buildup of junk under the gravel that can ultimately lower PH and other problems. If you have fine gravel in relation to fish size you will see the fish rooting through it and gravel exiting through it's gill plates, with coarser gravel they just suck it in and spit it out. At least one of my a. wittei used to suck in a marble sized pebble and swim around while rolling it around in it's mouth, a most interesting behavior...
I'm not sure about the snails. But my substrate is abouts two to three inches and it will dig through that quick.
