    I've noticed a few small slugs (3 to 4 of then) that live in the Zoanthids I placed in the tank, they are small < 5mm they don't seem to be doing any harm to the coral they are a pale brown and white must I kill 'em?

    I also see some tiny shrimp that live within the polyp colony I guess they are okay?

    Jpg,

    Not sure about the slugs but the "shrimp" you are talking about are more than likely pods. They are tiny harmless and very beneficial crustaceans that help clean up left over food etc. I have never seen a marine tank without them.

    I'd say if you can't see any damage, let the slugs be as well.

    I've thousands of tiny white (around 1mm) pods that the Fire Gobie eats all day (the pods seem to multiply rapidly) what are these?

    They are all pods. There are literally hundreds of different species of amphepods, copipods and whathaveyoupods.

    And yes, my Gobies go bananas over them as well.

    The slugs could be flatworms or nudibranches, we will need a much better description or even a good photo to help you identify what they are.

    Hi Jpg - you will see your zoanthid polyps shrink in, and become "pimple like" if they are being preyed upon (they also react like this when they are not happy at all)...
    BUT, as long as they are completely open, and looking "happy".... then things should be ok...
