So I have goldfish in a 36 gallon tank, and am moving them to a much bigger tank, but I was thinking about putting clownfish in the 36. I know nothing of saltwater fish, or how to take care of them, and if i decide to go this route then I'll buy a book and really research it, but my question is, would a clownfish fit in a 36 gallon tank, do I need corral or anything like that with them? How many would fit, and what else could be put in there that would also fit?
