A lady from answers.yahoo.com had a question about it and I do not know what it is. Is it harmful? She said she does %50 w/c daily. The betta lives in a bowl with no heater and filter. Please help, others have already informed her that the betta should be in a bigger home. http://i559.photobucket.com/albums/ss33/mizz_cass/033JPG.jpg I appreciate it.
