I had some about 6 or 7 years ago and they were stunningly beautiful. They are the perfect substitute for people that may not be able to get a very large tank for dovi's. Pretty much the same temperament not quite as brutal. A very slow grower is the only knock for some people. But for me it was not an issue.
