one spot fox face or tang?

[Amadod2]

So after a long battle with bubble algae I notices today in my tank there were 3-5 small bubbles that I removed by hand...this leads me to this, I don't want to go through another bubble algae outbreak as I once did, so my question is what fish would be better for a 70g tank a one spot fox face or a tang? i have been reading online about the one spot fox face and they seem to be great fish with the exception they can nip on corals, i do have sps and lps and with all the tangs recommend out there it seems it would outgrow my tank which I'm ok with as i would sell him/trade him etc. any thoughts or experiences?
