Not sure how large the tang is but a 55 is not suited to this type of fish long term.
In terms of feeding, pearlscales I've kept will eat pretty much anything. Give it a lot of meaty foods to include mysis, chopped scallop, mussell, clam, Marine Cuisine, Emerald Entree, etc. Pellets are good, occassional flake, and greens like nori. They're a relatively hardy fish as butterflies go but won't do very well with aggressive mates. Hopefully your tank is well established and has a lot of live rock for shelter and grazing. Butterflies do best in systems like this.
I agree with the concerns of the sailfin tang. The sailfin is still for the most part small & comfortable in the 55g tank.
I'm thinking after QT time period of butterfly & goby. I will add a divider separating the Butterfly & Watchman gody from sailfin & falco hawkfish. This way the butterfly can become acclimated in peace & the watchman can dig a hole & become comfortable in his new environment.
After 4 or 5 days remove divider & watch sailfin & butterfly.
If sailfin harasses butterfly, I'll remove sailfin & put in QT for a week. Rearrange Lr to a degree, then add sailfin back in DT.
If that doesn't work, I'll pull sailfin from tank & sell him at local fish store. Buy another sailfin much smaller then butterfly.
I don't have any problem selling the sailfin because i accepted the responsibility of selling the tang when it outgrew the tank.
More opinions about housing a Pearlscale would be appreciated....
