Curious, I have a horse-faced loach and he doesn't burrow. He likes to sit in my plants. Is that a good sign or a bad? I've had him for quite a while and I think he's grown since I got him and seems to be happy, but I was told when i bought him that he would burrow and I haven't seen him do so. Why might that be? Does he just not like to burrow, do you think? Does he not like gravel? I'm just don't know.
