Are these compatible

[jstlstn]

I am almost certain the green and red one is an Acan, not sure about the orange one though. The question is can I grow them on the same rock? I want to start an Acan garden but not sure if these two are compatible. Any assistance in ID of the orange one and suggestions are great appreciated.

Bottom looks somewhat Favia/Favites and if true, is semi aggressive and will sting neighbours.

Orange one may not play nice. I wouldn't put it near the acan. Check it out at night to see if it had sweepers out
