Pink lemonade aggressive?

[bct15]

I had placed a decent sized (4.5 inch) acropora walindii colony somewhat close to my nano fraglet colony of pink lemonade, about three - four inches separating the closest part. After about a week the tips of all of the branches facing the pink lemonade have skeleton showing and there is a smal bit of recession near the base of the pink lemonade on the side facing the walindii colony. The walindii was in the direction the pink lemonade appeared to want to grow. Is this signs of sps warfare? If so, who is the aggressor (started it) walindii or pink lemonade or both? I have moved the walindii colony away now.

I've never seen acros fight at inches apart...I'm thinking there is another villain.

Not the Lemonade IMO/IME. Acros need to touch to fight.

Agree with above... Very doubtful an acro could sting a few inches away. Sound like burnt tips from alk or just as likely a fish is nipping the tips.

This is what happens when you get wild pieces and dont QT them.. theres always a chance of intruducing something
