I think I got that batch in Sept-Oct 2004 and got rid of the last of them in March 2006. They were decently colorful, but since I hadn't had a true pair form, I was going to free up their tank for something else.
I had a female for awhile. Grew to about 6", very nice color(s). Dug a LOT! Pretty nasty with my other fish (she was the dominant fish in the tank); that seems to be unusual, based on what others have written in the past.
