so i bought and setup a 40gallon today with water and media from my 180 letting it settle for a couple days while girlfriend decides her fish. its "her" tank but i'm going to add 5 clown loaches to let them grow a bit before adding them to my tank. 16" s. weeksii might not be friendly to these tiny tiny clown loaches available at all the stores around here. anyway any fun/colorful suggestions for a 40gal thatll have a handful of growout clown loaches in it?
