What size of tank would you go with for larger fish?
 

I am planning on having a reef tank but I also want larger fish like Blue Throat Triggers and tangs. What size of tank would you think is a minimum to go with for these kind of fish?

Heads up: you can go small but you can never go big enough when it comes to reef tanks with tangs ;)

tank
 

as big as you can fit.i have a 240 right now and planning on a 300-much later around a 2000 gal

6' or longer for tangs would be my choice. If you get small size tangs eventually you will need an upgrade. I have a 8' - 165 gal but in the process of building a 8' - 300 gal.

Yeah I was planning on going a 6' long tank just to save some space length wise but going around a 180 to 240. I am just wondering because I need to consider costs of running that much water plus the sump.

Six foot minimum for tangs
 

As usual Grizz is right. Six foot is a minimum. Tangs are swimmers. They spend all of their time swimming to and fro and require the length that larger tanks provide. Thank you for asking.

Well thank you guys for answering. :)
If I am going to be dropping a fair amount of money on an upgrade I want to make sure that everthing is going to be right for my fish and that they will be happy.

Its been often said that in Marine bigger is better. If you own your own house, build as big as you can fit!

Very well put. Do you own your own house?
Where are you going to put the tank?
Can your floor support the tank?
How big are your doorways to bring a tank in or build one on site?

You need a 5000' long tank minimum.
