So my 20gallon mixed reef has a double pest problem. Half of my rocks have gotten covered in blue clove polyps so a lot of my zoas are being choked out and they are starting to irritate my gonis. I just got in some fenbendazole to try and poison the bcp. The only problem is I also recently added about 6 berghia to knock out some aiptasia that have re popped up after my first round of nudis knocked them back. What are the chances the meds kill the berghia. I know I’ll have to relocate my snails into another tank for a while but I would like to continue to let the nudis do their work.
