how do you frag a cata ?

As subject, how do you frag a 3 mouths Catalaphyllia jardinei
I would try to split each head as it has lost the frag (and the calcium part attached to the frag). Actually i've fixed the cata to a rock by using a rubber, but i don't like this system

Any idea ? (CA glue doesn't stick to the soft part of the coral)

No idea on either, but I'll give you a bump.
