I have nems that settle close to my euphyllia some are torches. The nice thing is that nems can move if they are getting stung. I personally let such things sort themselves out untill it seems my intervention is needed. If the nem gets stung and moves over a bit fine, if the coral starts taking stings i move it if needed. I have green bubble tip that settled so it extended into my frogspawn. Neither seemed bothered so i left it. Evidently there was some iritation bc the frogs9 split and grew around the nem with heads extending far to each side. Then the bubble moved lol. Heres the piece with splits 1&2 my nem used to sit where the x is.
