A 20 long is 12" wide, 12" tall, and 30" long. I agree with you. I'm looking at my 20 long right now and thinking 'no way would I put a dwarf fuzzy lion fish in here!! You also need to think about how much space enough rock is going to take up, especially since you aren't running a skimmer. At best he's gunna have just enough room to sit there and not really be able move.
