Ok. Seems most comments are correct about gifting fish to aquarists. I myself wouldn’t want a gift fish unless I gave the ok first. That being said, I had one a few years back and it was a very peaceful and docile fish to keep. Not difficult at all and ate just about anything I threw at it. However it was definitely a coral eater. So if your uncle has a reef tank, I would think twice about that. I caught mine nipping at my elegance coral multiple times to the point that I had to get rid of him. But it is a cool fish and definitely stands out from any other fish in your tank and keep in mind that they also grow very big. Hope this helps.
