I have a rock that has some aptasia on it my problem is i cant use peppermint shrimp as it has christmas tree worms on it and from what i read they will eat emm . also i read using aptasia x will just cause the aptaisa to release spores and make my problem worse <this is from what i read not sure if its true > . i know i can get those nudibranches that eat emm but i cant afford that and i know copper banded butterfly eats emm but are they safe with corals and other inverts ? what other options do i have ?
