Thank you so much for the links!!! I learned a lot more about these great fish. Like the guy in the first article, I have developed a great fondness for bottomfeeders. I have 2 Cories as well, as soon as I get another tank, I plan on getting some different types of fish that I haven't yet had.
I may crack down and get a 20 gallon as soon as I can afford it. I hear they are a lot easier to take care of, plus they are better for the fishes and their wellbeing. Not to mention the potential for having a kickass planted tank.
Again, thank you.
