Can My SaltWater Fish Get Along?

[Almostmikko]

I have a Blue Tang, Yellow Tang, 2 Clown Fish, a Porcupine fish and i think its called a Niger Triggerfish, so far none of them are fighting or anything i just want to know if they get along.
The tank is probably 35-40 gallons but so far none of them are hurting or biting each other im just curious.

In what size tank ?

Return everything except the clownfish. You cannot keep the others in such a small tank.
