-> me when I first got them. Please check what your KH, hardness and
-> pH are. It sounds like a problems that a friend of mine here on Oahu
-> has. Where I live in Manoa (the valley of rainbows, really ;-) we
-> have magic water that prevents this. However there are those that
-> will suggest that a steady diet of white worms are much too rich for
-> most bows, too much fat.
-> check your water and let me know. I can probablly get a bunch more
