Just out of curiosity is it possible to have a successful reef in a little tank? By little I am talking like 10 gallon? Reason I ask is because I got to pull two damsels out of my big tank that my wife bought and I figured since I have a 10 gallon just sitting around i will put them in that. Also figured that if I'm gonna have a mini tank for her fish then I might try to do a mini reef.. lol. Thought? I know you can buy a biocube and such but that's like 20-30 gallon and I'm not looki g to buy another tank when u got one sitting here already
