Dear hobbyist,in my 150 gallon aquarium I have 4 tangs .
A Clown tang - 7"
A Hippo tang -5"
A Blond Naso tang -7"
and a Yellow tang - 5.5" . I also have a cleaner wrasse living with them,which keeps them clean. Of all the tangs I've ever had,the yellow tangs' the hardiest. Tangs need good water quality, seaweed,spiralina,and foods enriched with vitamin C . Enjoy the hobby.........
