Recently I noticed that my tank was becoming very cloudy. I soon discovered that my wife was assisting in the feeding process! She said that every time she walked by the tank, they all swam up and looked at her, so she fed them! At any rate, it was obvious that the cloudiness came from an excess of bacteria eating the extra waste. So, I cut back on feeding until the tank cleared up. Now, about the angels... I have 2 juvenile angels, both had beautiful dark stripes. Until the fasting began... They seem completely healthy, swimming, eating, no problems. However they are almost completely washed out, colorwise. They will only show their stripes at feeding time, otherwise they are silver with no trace of a stripe. Is this normal? How can I get their stripes back for good?
