If you're asking how fast they grow, anyone looking at this thread would assume you didn't do your research prior to purchasing. So there's really no need to be so snappy! Also, it may not be fair, but most of these fish, as well as other monsters, never get the 'gigantic' tank or pond that their owner intends, due to a variety of reasons. Most of the people on this site know this, and so they discourage people who don't even know how fast a fish grows from buying the fish, until the research has been done. No one is trying to be mean.
