Are my Euphyllias playing nice?? UPDATE: HELP!!

I have an aussie wall frog next to a tri-color purple wall hammer. I have noticed what appears to be a sweeper tentacle coming from the frogspawn that keeps brushing the wall hammer on and off for about 2 days now. I was told at my LFS that these could be kept really close together without issue.

Could this cause a problem?

Some pics of the sweeper tentacle:

 

Not all Euphyllia an be kept in close proximity to one another, most can but you have to watch for aggression. Considering that Euphyllias may be collected from significantly different geographical locations it more surprising to me that different types do not have more aggression problems.

And to answer the rest of your question, yes; that WILL soon be a problem.

 

okay thanks! and good point, ill move them apart first chance I get then.

 

Okay so i moved the hammer as i said i would now its doing this.... its very weird! Chemical warfare, expelling zoothanthellae?

Click video to watch:

 

Looks like the Shrimp or something startled the coral, a reflex response. It's simply expelling fluids in response to contracting. Could have a slight dusting of detritus on the surface as well.
It's not uncommon for LPS to expel waste, bi-products of metabolism.

 

As a general rule I try to keep frogspawns hammer and torches seperate. I know many have had success with them touching but why risk it on a $60+ coral? I will have hammers touch hammers and frogspawn touch frogspawn but do not have hammers touch frogspawn and etc.

 

its done it like repeatedly every few minutes, if that changes anything. but thanks everyone! everything seems normal otherwise
