Went to the zoo a couple week ago...The exotic aquarium had a normal gold fish and an ah angel fish. All tanks had ick and green algae and I would venture to say they doh have anyone managing anything. If yu think I'm kidding I'll post a pic of it when I have time. I was telling de wife that the tanks are the same as when I last was in the zoo, and that's when I was 11 yrs old. My tanks home would put anything they have to shame and it doh cost nutting to setup. Hell if they want, pay for my ticket and the vacation time and I'll set up one massive salt tank for free. I could probably redo the entire fish room in a month.
