Bro,
If u want to be able to maintain SPS with it's vibrant colours then you need to do the following:
a) have a stable water parameter like almost 0 nitrate and phosphate, high MG and Ca as well as a stable KH.
indirect flow as previously advised
c) strong intense light
So in order to achieve that you definately need some relatively good equipment to do like the bros above have advised... unless you want to be very hardworking and do the necessary like very frequent water changes; always measuring your water parameters and topping the necessary up etc
For starters if u are game, then try monti frags..digi...bird....If they thrive then you know you're ready for greater things...
