I just found that these little monsters have been eating my rainbow monti. Its the only monti that i had in the tank and thankfully it was just a small frag. I have since fragged about 1" out of the 2.5" colony and have tossed the rest that I saw they were on. It seems like they were eating it from the outside in. I was wondering how aggressive I should tackle this issue. Ive just learn that they are the absolute worst hitchhiker. Should I do the dipping every other day as BRS recommends? Do they only live on the monti or are they now in the entire tank?
