I just installed K2 on a Joomla 2.5 install. I got the following message:

Notice: K2 Content Elements for Joom!Fish were not copied to the related folder, because Joom!Fish was not found on your sytem.
Installing component was successful.

I did a search for Joom!Fish and can't determine what I need. Can you direct me to the right area to download and install this?

Thanks,
Anna
