A 55 set-up is not fine for a yellow tang. A small juvenile yellow can survive (not live survive) in a 55 for perhaps a year or maybe two if they are small enough when purchased. However, as they mature to adulthood they require at leat 6 feet of swimming space. Yellow tangs reach about 8" as adults and cannnot live in a 55 long-term. Glad you have a larger set-up planned...hope your tang survives in the interim.
