Geek, you should do like 90 gallons for your boss and ask him for a bit larger budget and make him a discus tank. My 125 is housing 7 discus right now and it is a beauty man. You like to order fish online, but I go to discus breeders that have good quality juveniles for $25 a piece. Think about it. Discus are my favorite freshwater fish, but also the hardest fish to take care of in my house. I have my first marine reef tank as well. I found it on craigslist for $80 for everything including fish and live rock.
