What kind of tangs are fit for a 75 gallon tank

[lastlight]

The 6 foot argument is pretty weak if you give this much thought. All shades of the same colour and all of our tanks are too small. naesco your old bull nose 6 footer was one of the smallest 6 footers you can buy. Personally I'd aim for a tank with the length and turn around width of a standard 180 as a feel good minimum for anything besides your kole and similar tangs. In the end it's us feeling a bit better about keeping things we really shouldn't. My tank is over stocked as far as tangs go too with just two! I find it a bit amusing that the tang police front man on canreef had as many tangs as he did in a tank that was what... 135 gallons? My kole in my 97 was likely more comfy than the acanthurus species in your old tank.
