Answer
Hi Lynn:  you should be cleaning your tank on a weekly basis... 10-15 percent water changes and a good gravel vacuum.  You can use a razor blade or hard plastic scraper to clean hard to remove algae off the glass.  Feed your fish only what they will eat in 3 minutes of time. I feed mine twice per day.  keep me posted... dave
