About a week ago one of my smaller clown loaches started to burrow under a big rock (don't worry, its diagonally suspended, one end in the substrate and the other on a piece of driftwood), so i tought he was searching for some MTS and went to bed. In the morning the wife noticed a big sand mound besides the rock, seems like one of my big momma Yo-Yos had taken over the digging and now has a cave underneat the rock
