I've never had a saltwater tank before but when I went to a local fish specialist store at the cash they had what appeared to be an 8 gallon hex with live rock and a bit of like ... i don't even know what it was.. just stringy purple stuff that looked kinda like a plant... Inside the lil tank was a clown fish 
I was wondering what the minimum size of a clown fish tank could be? I really want to setup a tank like that but maybe it's too small or something?
i have no experience with salt water but i've got a 20gallon fresh D:
