The first one is a red bug.......which is known to eat other corals besides sps.....but love sps.

The second one is a montipora nudibranch....just an example.......but a nudibranch will go to town on corals......and can multiply rapidly.

The third one is a normal amphipod. Copepods are microscopic and cant be seen with the naked eye unless they are full adult, and then they are still smaller than a ball point pen head. Amphipods have been reported to eat meat....such as human or what ever they can get there jaws on. There is a (man eating) amphipod as well.....they have found them in shipwrecks where people have drowned...You could have a (man eating) amphipod. BUT. No matter what they are of the last three......you have to do an Iodine dip. I brought this matter up to my buddies in the reef store and the club.....and the consensus was that no matter the animal....flatworm.......nudibranch......copepod...what ever....the only way to rid it is to dip it. Are they still eating your coral?? And make sure you dip ASAP, because the longer they sit in your system......the more babys...
