Suitable tangs for 4ft tank

[Leah]

When I started I didn't know about the 4 ft rule but I have 2 tangs in my 72 bow. Not
sure of the exact measure. I first had a yellow tang and It grew large and mean. Sold
him and got a smaller yellow tang. I also have a hippo who is growing by the minute. If
I could get the yellow out I would. I did have a book that tells you how many gallons are
needed that was what I went with. I also have a 95 gal with 3 tangs in it.
