Going to be re-done here shortly, as some tank mates will be moved to my other tank. Also have to get the algae back under control. This month work has been out of control and been neglected. Most of the feeders were given to us free (guy at lfs hooked us up to help make it through the holidays). Going to try to get them of live food soon (hopefully)
I bought them a couple months ago at 2 inches max. They have at least doubled in size. Started with guppies and now I am on small goldfish feeders. I do feed their tank mates frozen bloodworms which they used to eat all the time, but nearly as much now.
