frag

I'm going to be starting up a small 10 gallon reef tank soon (my first time dealing with salt water), and I have a few questions about adding coral that I couldn't seem to get from googling. Heres a list: 1. I'm going to be buying frags at my LFS with the plugs on the bottom, do you need to...

its green button polyp which I got a for free! But it didn't open! Is it fine or is anything troubling it?

I am thinking of setting up an anemone tank. I might use a 10 gal I have or a cookie jar or maybe a wine bottle on its side. I understand the need for sump, skimmer & flow, I want to know what will happen when the anemone outgrows the tank? Will it be sad, die, or just stop growing? Can I frag...

Iam looking to keep gar and bowfin along with some other large fish like P. Bass and atf and water cows. Will a frag tank work better for this or get a larger normal tank.

So I got a pair of Ricordea florida and one of the two polyps has an extra mouth. Could I frag it? And would it be easier to frag with the extra mouth already there?
