Number of fish in a 55 gl

[Coralgurl]

I've got a picture of the tank on my profile, I don't know how to get it from there to here.....

We've got a couple of those worms in our tank, they get really excited when I feed...lol.

I've been happy with how the tank has been running for the last little bit, everyone happy! I just noticed my bubble coral has new bubbles and is growing, this guy gave me huge heartache a month ago!!

Wondering - is it hard to go to a bigger tank using existing equipment, rock, sand, or would that tank have to cycle as well to start?
