hmm, i want dithers for my 120g. My wild oscar is a WILD MAN. I was thinking abotu going with giant dianos because they get to 6" and are so quick, but silver dollars would work too I am sure. I am easy, i have a ton of CPD fry that need foods, I have discus that love worms in general, and my bichirs just love food. I am certain we could work something out. We could meet half way so its less of a drag for either of us, or you are more than welcome to come to my home and hang out, pick out your snails, and have fish geek talk.
