I think you're pushing it with that many tangs in a 180g. It may work out for you but odds are against it. And as stated above the Sohal and Sailfin get huge. I've got a SF in a 225g. I've had him for 2+ years, (he's about 6"), and the bigger/older he gets the more possessive he gets of his space. Although he gets along with his tank mates, anything new coming in the tank gets his attention right away. He will even attack the feeding stick or other inanimate objects. Small, juvie tangs are a whole lot different from large mature tangs. As for the Sohal, IMO, nothing less than an 8' tank will suffice. However you decide, good luck with them. :biggrin:

well i really wanted either a clown or a sohal and after everyone said clown is hard to keep i decided to go back to sohal.

Im willing to give up the sailfin and just keep the sohal on the list, hows that sound?

Most sohals are very aggressive, the smaller the tank you have the more aggressive they are. I know people who couldn't keep one in their 230g tank becuase of how aggressive it was to other tank mates, you could try it but odds are it will outgrow your tank fairly fast and take it's aggression out on other tank mates.

Have you considered a Kole Tang. They are great algae eaters; are a smaller species; don't require as much space as other tangs; and a different species/colouration from your other tangs.

i had kole on my list but im not sure of the color (too dark for me). I love the colors of the sohal and clown and purple. Im looking for color. Is there another tang that has nice colors like the sohal and clown? I remember when I first saw a sohal i was like, WOW i want that fish in my tank.

Oceanic had some lovely tangs when I was there on Sunday.. Tangs are a hit and miss in any size tank imo. They can fight until one is dead or just until they claim a territory. I have a Purple, Sailfin, +{2} Yellows, all in my 90g, which is the temporary tank until the 150g is set up, but even though I got these fish when they were quite small, they do get large.

what tangs did they have? purple or powder brown?
all the fish ive gotten from them have been awesome so far.

Chevron tangs are nice but hard to find, and hard to get eating. They also get darker as they become adults but imo they are really cool.

chevron tang was on my list but i took it off because i didnt want to hunt one down for 324342343 years.

Your tank is large enough to accommodate several tangs.
When you choose them choose them on the sole basis of health (nice and plump, clear alert eyes, no tears or spots) The tang should be just as interested in you as you are in it.

You want colour
For the blue colour choose between a regal tang or an Atlantic blue. NEVER a powder blue.
For purple, the purple tang.
For a mixed colour the power brown tang A.japonica (with orange on it)
For a different tang seriously look at the mata or maculiceps.
If you choose a sohol place it in the tank last.

When you are ready to buy and before you buy ask again for tips to avoid fighting, death and aggression from the reefers who successfully keep them.
