I have a large sohol in tank with other large tangs...Unicorn, vlamingi, male blonde nasso
Tank is 8"x3"...about 240 gal...he/she loves to swim.
He/she was the last fish added so not too aggressive towards other fish..but that can change given their reputation.
If you are considering, i would add as the last fish-if not, any fish after may not fair so well..
