Given that loaches tend to dig themselves into the substrate, or under decor, it's probably best that fine gravel or sand be used.
However, can anyone advise on how they make out with standard aquarium gravel? Can they dig, and is there a high risk of injury? Or will they thrive just as well under those conditions. I'm thinking of a couple of khuli loaches for my tank.
