I'm not rocking anything special experience-wise, I've only got two 55 gallon tanks at home. I just assumed that I'd be able to handle a 20 gallon for the next 2 years while I'm finishing school. I realize that makes me nothing on this board, but I thought I could get sound advice. I assumed toning down my ambition to a small tank was reasonable. I'm sorry to offend so many of you by not being on your level, and I apologize that I thought I could find help here.
