Question about tank size + sump

[jester805]

I would like to get a Powder Blue Tang, but I've read that they need 100 gallons. I have a 75 gallon display tank with a 20 gallon tank.
When a tank size is recommended, do you only look at the size of your DT? Or can you add in a sump / fuge if you have it?

For example, I have 75 DT + 20 sump = 95 total gallons.
Thanks!

Depends on the situation but here you would have to go by the display only. Tangs need room to swim... personally I'd have to say a minimum of a 6' tank regardless of how many gallons it holds.

Thanks for the info. I thought it would probably go by swimming room, but wanted to make sure. :thinking:
