Wow, that's one beautiful little sucker
Good luck with him!
A word of advice: Nuggets are notorious for being hard to acclimatize: unfortunately many die during the first weeks, due to improper acclimatization by the importer/retailer. Often they are sold before the bacteria in their digestive system have the chance to adapt to the change from living in the wild to a life in captivity. This causes problems with extracting nutrients from their food, which means they can literally starve to death despite the fact they are eating.
So keep an eye out on him the first couple of weeks, and act as soon as you notice a sunken belly or eyes - if caught in time, there's a good change of recovery.
