Rearranging minipets?

Hi, silly question.

I dedicated a fungal wallow to my HoM last night to be all nostalgic because it was my first mini ever. It's a horrendous thing though, and it's making my other shiny minis sad.

So I was wondering, once I hit 20 can I continue clicking rearrange until the 20 other minipets are showing up and the 1 fungal wallow is hidden? Or is the first 20 minipets dedicated the ones that will eternally show up?

Thanks! Just wanted to know before I dedicated a Moa that wouldn't show. ^^

You can change those which are shown, however you cant completely customize it, there are a set couple of patterns which cant be changed, and you have to chose from one of them.

I dont know for sure, but I would imagine there is a way to keep it in the back, or out of sight. Play with it
