The effects of AEFW and Red Bugs are on two ends of the spectrum. Although it is not considered good practice to pass any type of pest around, Red Bugs get passed around more times than Red Lane workers on the weekends! Sadley enough, most of the people don't even realize that they have red bugs until they pass it to somebody else. Treatment is really easy and works fast if using the correct dosage. As for AEFW, they are really harsh on the corals. The only possible way a system can sustain acro eating flat worms is if they have a fish that will eat there. Even then, you are pushing your luck.
