	cardinal color fades nightly
Beefshank Enthusiast Posts: 246 Kudos: 141 Votes: 36 Registered: 30-Jun-2004	I have a new school of 10 cardinals, and I have noticed that their red bottom stripe fades to...."brown/gray" at night. The first night, I was worried, but in the morning, they were red again. It seems to happen every night, (I've only had them for about 6 night so far) but they are always viberant in the morning. Is this common? The fish all seem fine. thanks, -Dennis

Don't worry, it's perfectly normal. As long as it comes back when they wake up. [span class="edited"][Edited by 2004-08-30 23:15][/span]

It's not a very good defense though, as their bright blue stripe still shines great. I guess they are lucking nobody is hunting them in my tank! -Dennis
