I have a game I am playing with my 150. I have been introducing clown loaches into it to see how many I can get in there and still not see them. I don't know why but they rarely come out. About once a day I will see one or two. I am up to 10 and only can catch the majority of them out at night if I drop food to the front of the tank. I was very curious where they go most of the time. I have a lot of rock work and plants so there are places to hide but I didn't think there was that much hiding area. I started moving things around during a water change and found a whole nest of them. They had dug themselves under a flat rock into the sand below. They were nose to tail and stacked on top of each other. Its funny because it is a peaceful community tank and nothing bothers them. I think I'll get a couple more this week.
