The acro-eating flatworms are very difficult to see. The look almost like a slimy patch on the coral because they are transparent and sort of assume the colour of the coral. They are always found on acro coral.

Red flatworms get up to maybe 3mm in size and do most of their damage by simply reproducing in such numbers that they begin to cover ever visible surface of the tank. Red flatworms will mostly cover your sand bed, but spread up all over everything eventually. They don't target coral specifically.

Red Bugs are easily visible if your eyes are decent. They move around relatively quickly..maybe about the size of a pin-head. The "red" I've seen tends to look kind of orange color and is really their back ends.

Flatworms require very different treatment than red bugs. You need to figure out which you have before you start dosing your tank with stuff.
