yeah that's the one i'm gonna get too. i was asking my boyfriend about drilling a hole and decided it would be difficult to do without breaking it. our other options we came up with were to either make a collar out of styrofoam or acrylic to put between the top and jar with cord notches in them or, to make a bamboo fountain/filter/hood combo.it will be low flow. i just need to find the right light for it now. it would be cute to get the one gallon and the two gallon side by side.
