Hammers-is there a limit to them?

[Venzzla]

Can you add quite a few hammers together without them hurting each other (stinging)? I'm assuming there sting is ok to other hammers. I'm thinking about putting in 6 or 7 small frags in my 40 gallon tank.

They will not sting each other. I have 4 right now all touching each other along with a close frogspawn.

yeah, only torch corals will sting other euphyllia...
