I cut up my green-polypled toadstool--it was HUGE! I got 93, 1" or larger frags out of it (I paid $25 for my 1st 1" frag). What a PITA having to mount every single one on a plug/rubble. If I toss a bunch of rubble in the frag tank I have them in (on the sand), will a lot of them attach by themselves?
