I'm so sorry I haven't been on the forum in so long! Don't worry, I haven't forgotten this lovely website! I moved to a different county back in May 2011 and started high school in a totally different school district. So I'm still adjusting and studying hard, and don't presently have any aquariums. But once I do, I'll be right back on this forum!
