Hey everyone! I know that each zoa and paly have its own growth rate because i have several different types and they all have grown at completely different rates. now i'm asking if anyone knows the growth rate for a devils armor??? ive had one polyp for about 3 or 4 months now expecting that it wouldve grown another polyp by now but nothing! the stem has gotten thick and tall but still nothing. all my other zoas are practically exploding in the tank. any ideas??
