To give you an idea of cost so you can keep some softies and polyps, my 20 gallon nano tank cost me about a 1000 dollars to set up which included a clean up crew. That cost does not cover fish or coral. To set up our 75 gallon tank it only costed us about 1300 dollars. Small tanks don't equal cheaper. One might think this but in the end, the cost per gallon is much more in a smaller tank then a larger tank.
