Got a sailfin yesterday and its currently in aclimation box only other tang I have is a hippo that is a model citizen. Tsnk is 100gallon i know not big enough upgrading to a 72inch 100gallon in next 6 months. Im not worried about the hippo, ive heard sailfins can be aggressive. The sailfin is a good bit smaller than the hippo. Hes been in box for 18hrs now when should i release. The other fish are 2 clowns (pretty good size) leapord wrass, lime green wrass, valentni puffer, 2 fire gobys, 1 chromis he killed others, and 2 fat mollies in tank. Tank has absolutely no aggression issues at the moment.
