My 5" male marble con, "Jack", recently was upgraded to a 40g breeder tank. I'm not happy with how the light sand is washing his color out, but I couldn't afford 40lb of Tahitian moon sand either. And for the record, I hate the plastic plants with a passion... just can't think of anything better to do at the moment because he barbers every live plant I've tried to grow.
