I used to have a shoal of them that died when my tank crashed (heater stuck on) they were really cool. They danced around like a bunch of confetti lol. They didn't really dig tunnels but they had a tendency to burrow hollow spaces underneath ornaments and driftwood. Totally peaceful and awesome fish. I actually forgot they existed. I may buy some for my planted tank.
My dad told me a similar story about one that burrowed under an undergravel plate and eventually got too fat or was unable to get back out. He found a huge loach in the ribs of an ugf plate when he tore the tank down. He said he was "fat and happy" and was also a very pale complexion from being in the dark for so long.
They are crafty little punks. They'll get into any nook and cranny you can even imagine.
-edit- I've only had brown kuhli loaches, never black or striped.
