Every fish is different be it captive bred, raised, or wild. Do a quick search as there are plenty around with them. Pretty fish and amazing to watch grow. I personally do not have one but recently purchased the Milletseed when they became available. A lot of the nipping I see is curiosity and not permanent damage if that makes sense.
Biota's bio under the fish is correct as it relates to their personal experience (staff keeping them in their home displays) and hobbyist feedback. But again at the end of the day the risk level is hobbyist related. If I was to buy one I personally would go captive bred/raised because I like the estimated age and fact that they are eating prepared food(s). That is most of the battle when buying these fish. Also I would buy direct.
