I have a large damsel that I want removed from my tank and so I need to find a fish trap. I have heard of people using a two liter bottle to do the trick but have never seen a pic of one to know how to fashion it. If anyone has a pic of one or has used a commercial one that worked well, I would appreciate some info. The damsel is about 2 inches big, very skittish, and sleeps in the rockwork so I can't go after him at night. I've thought of using a hook and fishing line, but I can't bring myself to do that yet! thanks in advance
