Paul, I have just posted on a new thread on how I got my CB to eat better and a variety of different foods along with a video of it feeding you might be interested in.I posted this on another thread about my copperband but I will post it here also because very few people read my threads so no one will notice.
I have been searching for information on the lifespan of copperband butterflies and it seems that ten years isn't bad.
I have also read that they are very hard to keep (which I totally disagree with).
I also read their lifespan is between 4-7 years. Then I read an informative article about them that says they live about ten years. Then I realized that I wrote that article so it doesn't help me. ;Wideyed
I think a fish of that size should live about 15 years, of course I am guessing but maybe thats it. I have had many of them but I don't remember ever keeping them over ten years. They don't get sick, they normally just stop eating at about that age.
Mine wants to eat, it just can't focus on the food and misses almost 100% of the time so maybe that is her lifespan. If it is, I am happy. If it isn't, then she is not happy.
