New Tang: Smaller or Bigger??

[Bzar]

Hi,
I am thinking of getting a sailfin tang for my system, but have a small issue with my yellow tang. He's been in the tank a long time and has become somewhat territorial. That being said should I get a smaller sailfin or bigger compared to the yellow?

If this is for your 90, I wouldn't add a sailfin.

hmmm any suggestions for the bubble algae other than emerald crabs?

Go to your local market and get some of the wooden scures, ones with sharp ends on them, then when you are going to do a water change, pry them off and suck them up, or you can try netting the bubbles, just try not to pop them.
