Do you find your loaches skittish without hiding places or is the lighting low enough that they are happy? Just wanted your opinion, I tried taking them out but they just cr*p out constantly gills going like mental lol. Even with a tone of hiding places they hide all day unless I feed them, then they're out at night. I guess it's to be expected, I have no way of diming the light at it's a fixed unit with x2 30 watt tubes.
