Can E. Cristata touch hammer/frogspawn?

[SamMule]

My E. Cristatas are getting very close to my hammers and frogspawn.
I know hammers and frogspawns were reclassified as Fimbriaphyllia. Can't find if that applies to E. Cristata.

Whaddya think? Move cristatas or see what happens?

I would not allow any euphyllia to really touch each other except for hammers. IME, they're okay for a short time but eventually they start to sting each other, and damage is done very quickly. Personally, I would move the cristata
