I have 5 in my 75 and i rarely see an aptasia, but every now and then 1 of them gets away from them and grows larger. When that happens, i need to use aptasia X b/c the shrimp's won't go after the larger ones.
That's not to say a certain shrimp won't man up and go for a large one, but it's not common for them.
