Of course we'll want pictures. He's so lucky to be getting a nice big home!
Just don't overfeed him and take your water readings. You'll start to see how quickly the ammonia goes up. I'm going to suggest two water changes a week until the tank is cycled. If it was me, I'd do two 50%, but I know others will suggest differently. You can use the gravel vac with every other change.
Just remember that if your ammonia is reading .25 and you do a 50% change, you are cutting it in half. If it spikes to 1, a 50% change divides it in half..which is why it's important to watch and be prepared to change a lot of water for a few weeks. The plants will certainly help with the ammonia, which is why I always plant at the beginning.
Basically, do a lot of water changes, test your water every few days and don't obsess about the cycling. Just enjoy the fish. The tank will cycle all on it's own.
