Well, I just put some new montis today into my tank that I bought from a store, and guess what pops out? These little white nudibranchs on my new montis. I had done an iodine dip on these montis previous to putting them into my tank...Has anybody had any experience w/ these guys before? They look just like the zooanthid eating ones except they are white. I think I'm going to try to use Flatworm Exit again, like I did for the zooanthid eating nudis... Wish me luck.
